The Unit was a military action series that ran on CBS for four seasons from 2006 to 2009. It followed the lives of the men of a covert US Special Operations unit as well as the lives of the women they leave at home. Created by Pulitzer prize winning author David Mamet, the series was based on the book "Inside Delta Force". The book was written by Eric Haney, who was a founding member of Delta Force and served as senior technical adviser on the show.
The following weapons are seen in the television series The Unit:
The Kimber Custom TLE II is the sidearm of choice for the Unit's Alpha Team, including Command Sgt. Major Jonas Blane (Dennis Haysbert) and Master Sgt. Mack Gerhardt (Max Martini) as well as the Unit's commanding officer, Col. Tom Ryan (Robert Patrick). Some of the Kimber Custom TLE II pistols have rails, others do not.
Kimber Warrior
In Season 4, the Kimber Warrior was the sidearm for many of the Unit's members, replacing the Custom TLE II.
M1911A1
The M1911 is a frequent weapon seen in the series. Master Sgt. Mack Gerhardt (Max Martini) often carries one as his sidearm.
Colt Compact M1991A1
In Season 1's "Unannounced" (S1E10), a Colt Compact M1991A1 is seen in the purse of Kim Brown (Audrey Marie Anderson). When Kim is threatened by a man at the radio station, Rory is seen pulling the Colt on the man.
SIG-Sauer P225
The SIG-Sauer P225 is used by Sgt. Charles Grey (Michael Irby) with a suppressor in Season 4's "The Last Nazi" (S4E14).
SIG-Sauer P226
The SIG-Sauer P226 is the sidearm of Sgt. Charles Grey (Michael Irby) and Sgt. Hector Williams (Demore Barnes) throughout the series. Sgt. Bob Brown (Scott Foley) switches to a P226 after using a full size Glock in season 1. Charles uses one with a suppressor in Season 4's "The Last Nazi" (S4E14).
SIG-Sauer P229
The SIG-Sauer P229 is used by a former gang member turned US soldier as well as Bob Brown in Season 3's "Binary Explosion" (S3E9). The 229 is unusual since Bob usually packs a P226 and the soldiers are getting guns from US armories. Grey also uses one with a suppressor and laser sight in Season 3's "Pandemonium, Part II" (S3E2).
The SIG-Sauer P230 was used in Season 1's "True Believers" and also carried by Colonel Ryan in Season 1's "The Wall".
Glock 23
In Season 1's "Non-Permissive Environment" (S1E5), a Glock 23 is the handgun Jonas Blane's daughter Betsy (Angel M. Wainwright) finds in a drawer at the Blane's home. She later fires it on the range.
Glock 17
The Glock 17 is one of the weapons prominently featured throughout the series. Bob Brown (Scott Foley) used a Glock 17 in Season 1 before he switched over to the P226.
Beretta 92FS
The Beretta 92FS has been seen in the hands of SWAT members, Unit members, and US military CID agents. In the Season 1's "Dedication", Jonas carries a Beretta holstered on his vest.
Beretta 92FS Inox
In Season 2's "Bedfellows" (S2E21), Mack takes a Beretta 92FS Inox off a biker.
Beretta 950 Jetfire
In Season 1's "True Believers", Mack hides a Beretta 950 Jetfire in his pants that he uses on The Major. In Season 4's "Bad Beat", Bridgett Sullivan (Nicole Steinwedell) pulls a stainless Jetfire.
Beretta Cheetah
Bridget Sullivan carries a Beretta Cheetah as her sidearm in Season 4's premiere "Sacrifice".
Walther PPK
In Season 2's "Freefall", the Princess (Bai Ling) is seen pulling a Walther PPK on Mack and the other Unit members. In Season 4's "The Conduit" (S4E4), Mack pulls a suppressed PPK to kill a terrorist he was planning on bringing back to the US.
In the Season 2 finale, "Paradise Lost", Jonas takes out a Walther PPK/S from a rodent station and gives it to his wife Molly (Regina Taylor). The pistol is actually a Brixia 8mm Walther Blank Firing Pistol. As stated by MoviePropMaster2008, "I just checked the lower image against the one I have. Brixia Arms used to make this type of blank gun about 10 years ago, but their quality was pretty bad. There 'might' be some available, but the majority of the 8mm theatrical blank firing PPKs on the market now are made by Kimar or Voltran. What tips it off, is the writing on the slide (it is identical to the markings on my Brixia Nickel plated Walther PPK theatrical blank gun) and the hole drilled in the top of the barrel (where the ejection port is). This hole allows the flash from the blank round to fire upwards since the barrel is blocked. Also the magazine is a thin single stack type that only holds those skinny 8mm blank rounds."
Walther P5
A Walther P5 with a stainless steel finish is carried by Bob Brown throughout Season 2 and the beginning of Season 3.
Walther TPH
Mack uses a Walther TPH in the Season 1 finale "The Wall" when the terrorists attack the Unit and their wives at Ryan's private reception. In the Season 2 premiere "Change of Station", Mack turns the weapon over to the Unit armory as he turns in his transfer papers.
Heckler & Koch USP
The Heckler & Koch USP is the sidearm of both Bob Brown and Sam "Whiplash" McBride (Wes Chatham) in Season 4 and also seen used by a Unit member in Season 2. Also seen used by the Turk in the Season 2 episode "Games of Chance."
Heckler & Koch P7M8
A Heckler & Koch P7M8 is taken from a dead terrorist after the Unit killed them to steal their money. Episode 3 of season 4. Shown briefly but might appear again in the series. What looks like a P7 is used to kill a Nazi war criminal in the episode "The Last Nazi".
Remington 1866 Derringer
In the Season 1 finale "The Wall", Jonas carries a Derringer and uses it on men who attack the Unit at Ryan's private reception. In Season 4 premiere "Sacrifice", a Derringer was the backup for CIA operative Bridgett Sullivan (Nicole Steinwedell). It is possible that it's a DA38 Double Action Derringer made by American Derringer. The Remington derringers' barrels tilt up while the one in the show has barrels that tip down and when Jonas places it in his waistband it appears to have a double action trigger.
Smith & Wesson Model 10
In Season 1's "Exposure", a young villager is seen firing a Smith & Wesson Model 10 on the rebels.
Smith & Wesson J-Frame Model 60
Seen in the Season 2 finale "Paradise Lost". It was Mack's hidden weapon which was then used by his wife Tiffy (Abby Brammell) to threaten him before he took it back. Also seen in the Season 4 premiere "Sacrifice" as Mack's throw away gun.
Tokarev TT-33
The one seen in the series seems to be a chrome plated Tokarev TT-33 Pistol or some other copy. Norinco tokarevs are used by chinese officers when the unit fights them at the casino. Used by Jonas and Bob.
High Standard Sharpshooter M
Bob Brown (Scott Foley) was presented with .22 cal High Standard Sharpshooter M with wooden grips when he and Jonas visit a former Unit member in the Season 1 premiere "First Responders". Also seen (very briefly) used by Ryan in Season 1's "Exposure" (S1E11) in a flashback. Despite being a suppressed weapon, the sound effect used is that of an unsuppressed gunshot.
Kahr K9 M9098 Elite
In Season 4's "Sudden Flight" (S4E2), the head terrorist uses a Kahr K9.
Mauser C96
In Season 3's "Gone Missing" (S3E10), an assassin carrying a Mauser C96 is taken out by Bob.

Browning Hi-Power
The Browning Hi-Power is used by several characters throughout the series.
Makarov PM
A Makarov PM is found on a Spetznaz member in season 4, and identified by Bob as "9mm armor piercing Standard Spetznaz Issue". In all likelihood this is meant to stand in for an SR-1 Gyurza, though it is clearly a Makarov, with the grips being the most obvious givaway. One was also seen in the hands of an Iranian embassy guard in the Season 1 episode "Security."
Smith & Wesson Model 36
In Season 1's "200th Hour", Rudy Hartano (Tzi Ma) pulls a Smith & Wesson Model 36 on Jonas when he fears he's been double-crossed. In Season 4's "Sex Trade", a S&W is planted on a male student who tried to blackmail Tiffy.

Heckler & Koch MP5SD2/SD3
The Heckler & Koch MP5SD2 is used by Jonas, Bob, and Grey in several episodes, notably in Season 1's "True Believers" and Season 4's premiere "Sacrifice". Most of the MP5SDs in the Season 4 premiere were of the newer variants with the Navy trigger group.
Heckler & Koch MP5K
Jonas, Mack and Hector are all seen using Heckler & Koch MP5K submachine guns in the series. Jonas and Mack were seen using the newer Navy trigger group variant, while Hector was seen using one with the old "SEF" trigger. Bob also uses one in Guyana to cover Jonas's escape. In Season 2's "Sub-Conscious", Kim Brown (Audrey Marie Anderson) is also seen using one in a dream sequence.
Heckler & Koch MP7A1 PDW
In Season 3's premiere "Pandemonium, Part 1", an assassin goes after Jonas and CIA operative Mariana Ribera (Tia Texada) with a Heckler & Koch MP7A1. The weapon is also used in season 4 episode 15.

Steyr SPP
Hector also smuggles a Steyr SPP into a diamond mine to be used by Bob in Season 2's "Old Home Week". The SPP is the civilian verison of the TMP modified for full auto.
Škorpion vz. 61
Seen used by terrorists in Season 3's "Inside Out" (S3E5) and hijackers in Season 4's "Sudden Flight" (S4E2). One was also seen in the hands of an Iranian embassy guard in the Season 1 episode "Security."
AP-9
One of Dragovich's men uses an AP-9 in the attack on the Unit during the reception dinner in Season 1's "The Wall".
Hotchkiss "Type Universal"
Seen briefly in Season 2 Episode 12. It's implied that the US government is supplying the rebels with these, which is odd considering it's a French weapon.
MAT-49
At least one of the Indonesian rebels carries a MAT-49 in Season 1's "200th Hour".
Assault Rifles
Colt M4A1 Carbine
M4A1 Carbines are used by all members of the Unit, often with a 40mm M203 Grenade Launcher, and with an optical sight (normally the Trijicon 4x ACOG, Aimpoint CompM2 and/or EOTech 552 Holographic sight). Sometimes they switch with the HK 416s.
M16A1
While M16A2's are more prevalent in the series, the M16A1 is also featured in several episodes.
M16A2
M16A2 rifles are seen usually in the hands of non Unit members of the military such as regular Army units in Season 2's "Dark of the Moon". In Season 3's "Play 16", Mack was seen cleaning and preparing Hector's M16, including attaching a bayonet.
M16A4
In one episode, US Army soldiers can be seen armed with M16A4 rifles, identified by the removable carry handle/rear sight assemblies.
Unknown M16
In Season 2's "Natural Selection", Bob used an M16 during his selection training. It appears to be neither an A1 or A2, as it has an upper receiver with A1 sights and the heavier-profile A2 barrel with A2 handguards. Most resembles a Model 715 (Canadian C7), but until a better shot of the right side of the receiver comes along or the episode's armorer himself states, a definite ID is impossible.
Heckler & Koch HK416
One of the rifles that is used by the Unit members is the Heckler & Koch HK416 usually in the the D10RS sub-variant with a 10 inch barrel, with optical sights sometimes. Grey is the only one in the Unit that had his with a carrying handle attached plus a compact ACOG scope, the others usually have the EOTech 552 Holographic sight attached (in Season 3's "Every Step You Take" (S3E4), Bob's EOTech disappears and reappears a few times). Mac uses one in Season 3 Episode 5.
Colt Model 933
Colt Model 933s were used by Jonas, Mack, Bob, and Grey in the Season 3 episodes "Five Brothers" (S3E7) and "Play 16" (S3E8), but note that in episode 8 they switch to HK416s a couple times in a continuity error, which implies they are intended to stand in for them. They are seen outfitted with EOTech 551 Holographic sights, AN/PEQ-2s, Crane stocks, vertical foregrips, and rail mounted flip-up front sights, but strangely lack a rear sight, although one shows up on Snake Doc's rifle sometimes in another continuity error.
Heckler & Koch G36C
The Heckler & Koch G36C is carried by Sgt. Grey in the Season 1 finale "The Wall".
SIG SG 552
Both Jonas and Hector are seen carrying the SIG SG 552 in the Season 1 finale "The Wall". Grey also had one also in the second episode of season 1.
FN FAL
Several FN FAL Variants are seen in the hands of Jonas and Hector in episode 2 of season 1. Jonas uses one with iron sights while Hector's is fitted with a scope. These were the full length FALs and one might of had a wooden stock. It was hard to tell. In season 3, episode 4, there was a couple FALs used by the enemy.
AK variants
Variants of the AK are featured throughout the series. All members of the Unit is seen using an AK at least once throughout the series. Most enemies have also used the rifle.
M70B1
AKMSU
The shorty AKMSU carbines (AKM rifles converted with Krinkov parts kits and AKS-74U side-folding stocks) were used in several episodes.
In Season 2's "Johnny B. Good", each member of the Unit carries an AKM rifle fitted with suppressor and Surefire light on their mission to Iran.
Sa vz. 58
In Season 2's "Bait", the Georgian rebels who hold Jonas hostage are armed with Sa vz.58 rifles.
FN F2000 Tactical
Jonas can be seen using an FN F2000 Tactical fitted with a scope in Season 2's "Extreme Rendition" (S2E2).
FAMAS
The FAMAS rifle is seen in the hands of French Soldiers in Season 1's finale. Also seen in the hands of soldiers in South East Asia.
Ruger Mini-14
A Ruger Mini-14 is seen resting on a tree by one of the terrorist lookouts that Bob takes out in Season 1's "First Responders". Also seen used by a man in episode 4 of season 1.
Heckler & Koch G3
Heckler & Koch G3 rifles are used by rebel forces aiding the Unit in Season 4's "Flesh & Blood" (S4E17).
Heckler & Koch HK91
A Heckler & Koch HK91 is used by a boy soldier used by an arms dealer to guard his home in Season 1's "Eating the Young" (S1E9). Some are obviously non-firing replicas, likely done for the safety of the child actors.
Galil ARM
One of the guards fires at the Unit with a Galil ARM in Season 4's "The Conduit".
Shotguns
Mossberg 500 Cruiser
A Mossberg 500 Cruiser is seen among the weapons packed on a mule in Season 1's "First Responders" (S1E1).
Benelli M3 Super 90
The Benelli M3 Super 90 shotgun are the main weapons of Alpha Team members Charles Grey (Michael Irby) and Hector Williams (Demore Barnes) in the Season 1 premiere "First Responders". Also seen in the hands of the US Rangers that accompany them in the assault of the plane.
Stevens 512 Gold Wing O/U Shotgun
Jonas fires a Stevens 512 Gold Wing O/U Shotgun chambered in 12 gauge owned by the Oil Minister. (It seems that even high-ranking government officials cheap out on shotgun choice.)
Sawed off Double Barrel
In Season 2's "Manhunt", Jonas finds a sawed off double barrel shotgun from behind the counter of a white supremacist's hardware store.
Remington 870
Mack used a vintage Remington 870 shotgun while posing as a bird hunter in episode 4 of season 1.
Ithaca 37
The Ithaca 37 shotgun is carried by a harbor guard in Season 3's "Pandemonium, Part 2" (S3E2).
Machine Guns
FN MAG mocked up as M240
An FN MAG mocked up to resemble the M240 ar seen in use by French UN forces in the Season 1 finale "The Wall" and by US Army troops in Season 2's "Dark of the Moon". They are recognizable as the M240G due to lack of heat shield but most likely, these are actually original FN MAGs mocked up to look like the M240G. In Season 3's "M.P.'s", Mack is seen firing one fitted with the heat shield and synthetic buttstock.
FN Minimi (M249 Para)
Hector (Demore Barnes) is seen with an FN Minimi mocked up to resemble the M249 Para in his final mission in Season 3's "Five Brothers".
Browning M2
A Browning M2 HB is prominently seen mounted on top of humvees driven by regular Army in Season 2's "Dark of the Moon".
PK Machine Gun
A PK Machine Gun was used by African forces in Season 1's "Stress" (S1E2).
RPK
An RPK light machine gun was used by a terrorist in Season 3's "Always Kiss Them Goodbye" (S3E3) during the shootout in the aircraft hangar.
RPD
In Season 4's "Into Hell, Part I", one of the sentries that confront the Unit at the Syrian border is seen handling an RPD machine gun.
M60
An M60 machine gun is seen in the arms cache found by Bob Brown and Dr. Donald Metz (Michael McKean) in Season 4's "Switchblade".
M60E4 Mk.43 mod. 1
An M60E4/Mk.43 mod. 1 MG was used by Jonas briefly in Season 4's "Into Hell, Part I" (S4E7). The E4's distinctive picatinny rails on the receiver cover and forend, and the removable front grip are visible on Jonas' weapon.
DShKM Heavy Machine Gun(Browning M2 mockup)
A Browning M2 mocked up to resemble the DShK heavy machine gun is frequently used in the series. It's fired by Taliban warriors in Season 1's "Dedication" (S1E7), set up by Syrian forces in Season 4's "Into Hell, Part II" and fired by Mack in Season 4's "Switchblade".
Sniper Rifles
Mark 12 Mod 0 SPR
A Mark 12 SPR is used by Jonas in "Eating the Young" (S1E9).
M16A4 (Sporter Competition H-Bar)
M16A4s were shown prominently in Season 2's "The Kill Zone" (S2E3) where for some strange reason, the entire unit went into the field carrying them and their man that was pinned down was also carrying one. It was noted that Jonas recognized the sound of a "7.62" shot distinctly over the enemy sniper's weapon to recognize friendly's fire. The problem is that all of their rifles fires 5.56 including the man they were rescuing, who clearly was using an M4. At the beginning of the episode - Bob was training a group of potention Unit recruits and except for himself, they all were using these rifles. Propwise, these are probably the same ones used later in the episodes by the rest of the Unit cast out in the field. This rifle was used more as a sniper rifle, since they were all fighting in semi. One instance where Mack fired in full for suppression fire means these rifles aren't semi-only sniper rifles, but used in the same manner, also with 20 round magazines.
It's worth noting that the sound signature of the "7.62" that Jonas recognized was much beefier than that of a 5.56. Spartan198
Armalite AR-10
In Season 1's "Dedication", Bob uses an Armalite AR-10 was dressed up as a sniper rifle, most likely as a placeholder for the SR-25. It is not a SR-25 due to the the fencing around the magazine release, and the brass deflector. The SR-25 lacks both of these. Bob fires it on full auto while in the chopper, despite the fact that its trigger unit clearly lacks an "Auto" option, but this was most likely added in post-production editing because no casings are ejected and the dust cover remains in place.
Cheyenne Tactical M-200 Intervention
Two Cheyenne Tactical M-200 Interventions were used by Bob Brown and Hector Williams in the Season 2 episode "Dark of the Moon" to engage the enemy targets.
Heckler & Koch PSG-1
Mack used a PSG-1 in "Stress" (S1E2) with great effect. His rifle had a 20 round magazine in it.
Remington 700 action on Accuracy International Chassis System
A sniper rifle frequently used by The Unit is a Remington 700 action on Accuracy International Chassis System (AICS). Bob is seen firing one in Season 1's "Non-permissive Environment". Mack also used this in Season 4's premiere "Sacrifice". The action is a Remington variant since the bolt is not an AI design. The folding stock hinge and adjustable cheek piece are visible in the close-up, so this would be an AICS ver. 2. Also, AI L115 rifles are generally outfitted with Schmidt and Bender PMII scopes which this scope is definitely not. Also, unless the magazine has been removed (unlikely during a mission), the magazine on an actual Accuracy International AW/M will be protruding from the bottom of the stock. You can clearly see the paddle style magazine release in front of the trigger guard which would normally be blocked by an inserted magazine. This rifle is the same rifle used by Micheal Weston in Season 2 of Burn Notice. The giveaway is the scope rings are the same cheapies seen on Jonas rifle here. They should be heavy badgers or warnes.
Remington 700PSS
Mack Gerhardt (Max Martini) wields a Remington Model 700PSS rifle. These guns are chambered in either .308 or .300 Winchester Magnum. Seen in the new opening of season 4 and actually seen in episode 3 of said season.
SVD Dragunov
The terrorist Zjhokar is seen with an SVD Dragunov in Season 2's "Bait".
Blaser R93 LRS2
In Season 3's "Gone Missing" (S3E10), the Unit goes on a mission armed with the Blaser R93 LRS2 Precision Sniper Rifle as their sniper rifles. In the episode, the Blaser used a new type of ammo filled with mercury that was designed specifically not to overpenetrate. The rifles were handled by Bob, Grey and Mack with Jonas alternating with Bob a couple times. The sound effect used is that of a suppressed round when clearly none of the rifles were suppressed.
A Taliban warrior uses a Lee-Enfield No.1 Mk.III to wound a chopper pilot in Season 1's "Dedication" (S1E7). In Season 2's "Dark of the Moon" (S2E17), many tribal warrior use Enfields as they attack the Unit and the American forces.
SKS rifle
The SKS rifle was used by terrorists in Season 2's "In Loco Parentis" (S2E20). The rifle was also seen in Season 1's "200th Hour" (S1E3).
M1 Garand
In Season 2's "Silver Star", the M1 Garand rifle is seen used by US forces, including Jonas' father during the Korean War flashback.
M1 Carbine
In Season 1's "200th Hour" (S1E3), Indonesian rebels are seen carrying M1 Carbine rifles.
Marlin Model 336
The Park Ranger who gets shot in the Season 4 premiere "Sacrifice" is seen with a Marlin Model 336. Bridget is seen putting the rifle on the Ranger to distract the terrorist shooting at her.
Found in the cabin by Grey in episode 1 of season 4. It wasn't used but the black powder that came with it was used.
Heavy Weapons
M203 Grenade Launcher
An M203 Grenade Launcher is seen mounted underneath Jonas' M4 in "Exposure" (S1E11). Hector is also seen leading a group of US Army soldiers with M203's in "Dark of the Moon".
Cobray CM203 37mm Flare Launcher
M4A1 carbines fitted with the Cobray CM203 37mm Flare Launcher standing in for the M203 were used by Unit members on their mission to Iraq to rescue Betsy Blane in Season 4's "Into Hell: Part 1" (S4E7) and "Into Hell: Part 2" (S4E8).
FIM-92A Stinger
Bob Brown (Scott Foley) is seen taking out a helicopter with a FIM-92A Stinger in the Season 1's "Eating The Young."
Chinese Type 69 RPG
RPG's are seen being used throughout the series. In Season 1's "The Wall", Dragovich's men fire one at oncoming French forces. In Season 2's "Dark of the Moon", Jonas takes one from a fallen tribal warrior and uses it on the onslaught of the enemy. Both examples seen here are the Chinese Type 69 launcher (the Chinese version of the Soviet RPG-7). The biggest difference is that the Chinese RPG had only one pistol grip. The second hand has to grasp a carry handle on top of the launcher. The Type 69s in the series have an optical sight mounted on the launcher.
Other Weapons
M67 "Baseball" Grenade
The M67 "Baseball" Grenade is used throughout the series. Bob uses one to spike a mortar in Season 1's "Dedication". He also uses one in Season 3's "Every Step You Take".
Molotov Cocktail
A Molotov Cocktail is thrown by an embassy employee in Season 3's "Every Step You Take".
Bow & Arrow
Not a firearm, but it should be noted since Bob went "Ted Nugent" on the fake US National Guardsmen in Season 4's premiere "Sacrifice".
Wheelie bag carrying handle gun
In Season 4's "The Conduit" (S4E4), Bob and Jonas had these weapons disguised as the carrying handles for their wheelie bags. It appears each of the square extendable rods were hidden barrels that each load one round, possible .22 or something small. To fire, they collapse the carrying handle forward into the smaller rod like you would a carrying handle of this type and it fires both rounds at the same time. I don't know if this is a real firearm, but it acts like one. Meant to be used to disarm armed men with real guns.
