In the series premiere "First Responders" (S1E01), Command Sergeant Major Jonas Blane (Dennis Haysbert) carries a custom M1911 handgun of unknown make (it appears, based on the lettering on the slide, that a Colt Government Model may have been used as the base gun, however this is not confirmed). The pistol lacks the front cocking serrations frequently seen on Kimber models (which Jonas carries throughout the rest of the series), but is outfitted with adjustable sights, a combat hammer, a combat trigger, an ambidextrous thumb safety, a beavertail grip safety, a full length guide rod, an extended slide release, Pachmayr grips, and an extended magwell. This weapon is never seen after the pilot episode, which may have been deliberate, as the pistol would likely have been confiscated by base security after the shooting incident at the end of the episode. However, the more likely explanation is that the prop guns were simply unavailable to the filmmakers when shooting subsequent episodes.

Kimber Custom TLE II
The Kimber Custom TLE II is the sidearm of choice for Command Sgt. Major Jonas Blane (Dennis Haysbert) throughout Seasons 1-3 (though he occasionally switches to a Kimber Warrior). Sgt. Hector Williams (Demore Barnes) carries one at the beginning of Season 1 before switching to a P226.
The M1911A1 is a frequent weapon seen in the series. Master Sgt. Mack Gerhardt (Max Martini) carries one as his sidearm. In "Eating the Young", the arms dealer Adolpho (Luis Antonio Ramos) pulls a gold-plated M1911A1 on Bob.
In "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.
The SIG-Sauer P226 is the sidearm of Sgt. Charles Grey (Michael Irby) and Sgt. Hector Williams (Demore Barnes) throughout the series. Master Sgt. Mack Gerhardt (Max Martini) uses a P226 throughout Season 1 before switching to his M1911A1.
In "Non-Permissive Environment" (S1E05), a Glock 19 is the handgun Jonas Blane's daughter Betsy (Angel M. Wainwright) finds in a cabinet drawer at the Blanes' home. She later fires it on the range.
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.
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. Sam McBride (Wes Chatham) takes a 92FS from a police officer in Season 4's "Whiplash". In the series premier "First Responders" Jonas uses an ISS Beretta Non Gun to kill Grey's mule.
In the Season 1 finale "The Wall", Jonas carries a nickel plated High Standard Derringer and uses it on men who attack the Unit at Ryan's private reception. Jonas' Derringer has barrels that tip down and when Jonas places it in his waistband it appears to have a double action trigger.
A Norinco Model 54 was used by the rebel leader in Season 1's "200th Hour." Model 54s were also seen used by Chinese officers in Season 4. A Norinco is found in a bag of an escaped convict who used to be a Unit operator in Season 2's "Extreme Rendition".
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" (S1E01). In "Exposure" (S1E11), the pistol seen (very briefly) used by Ryan in a flashback. Despite being a suppressed weapon, the sound effect used is that of an unsuppressed gunshot.
Both Alpha and Bravo teams of the Unit are seen using Heckler & Koch MP5A2 submachine guns in "200th Hour" (S1E03). Also prominently used by the Unit in "True Believers" (S1E04).
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.
Dragovich (Yasen Peyankov) uses a Cobray M11 in his attack on the Unit during the Col. Ryan's reception dinner in the Season 1 finale "The Wall" (S1E13).
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 ACOG, Aimpoint CompM2 and/or EOTech 552 Holographic sight). Sometimes they switch with HK 416s.
Sgt. Grey carries a SIG SG 552 in "Stress" (S1E02). Jonas, Bob, and Hector all carry these rifles in the Season 1 finale "The Wall" (S1E13). (Jonas's is briefly seen with a suppressor).
Several FN FAL Variants are seen in the hands of Jonas and Hector in "Stress" (S1E02). 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.
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.

In reality, these rifles don't interchange parts, but it was possible since the gun is massively customized and practically rebuilt from scratch.Error creating thumbnail: File missingBob uses an AKM with customized shortened barrel in Season 2's "Extreme Rendition".
AKM
Seen throughout the series, but featured prominently in Season 2's "Johnny B. Good", where each member of the Unit carries an AKM rifle fitted with suppressor and Surefire light on their mission to Iran.
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.
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.
The Benelli M3 Super 90 shotgun are the main weapons of Alpha Team members Charles Grey (Michael Irby) and Hector Williams (Demore Barnes) in Season 1's premiere "First Responders" (S1E01)". Also seen in the hands of the US Rangers that accompany them in the assault of the plane.
Jonas shoots skeet with 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.)
FN MAG machine guns mocked up to resemble the M240 are seen in use by French UN forces in the Season 1 finale "The Wall". 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.
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".
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 Knight's Armament SR-25. It is not a SR-25 due to the the fencing around the magazine release, the SR-25 lacking this feature. Bob fires it on full auto while in the chopper, despite the fact that its trigger group 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.
A sniper rifle frequently used by The Unit is a Remington 700 AICS. Bob and Mack are seen taking aim with the rifle in "Non-permissive Environment" (S1E05).
A Taliban warrior uses a Lee-Enfield No.1 Mk.III to wound a chopper pilot in "Dedication" (S1E07).

SKS rifle
The SKS rifle fitted with an AK magazine was seen in "200th Hour" (S1E03).
Error creating thumbnail: File missingSKS rifle 7.62x39mm with bayonet foldedError creating thumbnail: File missingIn "200th Hour" (S1E03), an Indonesian rebel holds his SKS on Jonas. In this screenshot, it is important to point out that this is a Norinco SKS Paratrooper with the thumbhole stock and a modified mag well to accept AK mags. Clearly seen here is the bayonet lug has been removed and is just a squared off block. This was done in the 90s to comply with the US assault weapons ban for import. They were only imported to the US like this, it is unsure if this was a mistake as it's doubtful that someone would have imported it back from Asia.
M1 Carbine
In "200th Hour" (S1E03), Indonesian rebels are seen carrying the M1 Carbine.
One of the terrorists who attacks the wedding reception in Season 1's "The Wall" uses a Hi-Point Carbine. Despite being a semi auto weapon in reality, it is depicted firing full auto. Obviously that terrorist had converted that weapon into full auto.
Several Type 69 RPG's are seen being used throughout the series. In Season 1's finale "The Wall" (S1E13), Dragovich's men fire one at oncoming French forces. The example seen here us the Chinese Type 69 launcher (the Chinese version of the SovietRPG-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 PGO-7 scopes mounted on the launcher.
