The M1911A1 was the standard sidearm of American Forces during WW2, Issued to Officers, NCOs and those in positions where a rifle or carbine was not desirable the pistol quickly became a favored item among Allied troops for its stopping power. The M1911A1 is seen in various episodes most notably in "Points" being used by Ronald Spiers threatening both the doctor and the soldier who shot Chuck Grant. Herbert M. Sobel can be seen running with one in "Currahee". Joe Leibgott shoots a German officer in "Points" with a M1911. David Webster threatens a baker with one in "Why We Fight."
Colt New Service
Floyd "Tab" Talbert is given a Colt New Service revolver as a gift on June 4th 1944 during the episode "Currahee", he is seen armed with it in the episode "Carentan".
M1A1 Thompson
Also known as the "Tommy" gun the M1A1 Thompson was the standard issue Sub Machine Gun for US Forces in WW2. As such many of Easy Company's officers and NCOs are shown carrying the Thompson as their standard weapon. Notable figures include Ronald Speirs, Harry Welsh, Lynn "Buck" Compton, William "Wild Bill" Guarnere and Johnny Martin.
What is interesting is that, if you look at a pic of Speirs in the book "Band of Brothers", he seems to be holding an M1928A1 Thompson.
If you look very closely, in "Currahee" in England were Winters squad is behind the bushes (right before the Brit on the bike shows up) when Lipton talks to Winters if you look at his ejection port ( where the empty shells come out you can see the hop-up from an airsoft gun so it is clearly a Tokyo Marui M1A1 Thompson.
M3 Grease Gun
The M3 Grease Gun was the cheap, inexpensive replacement for the Thompson Sub Machine Gun; It is only shown in the hands of Roy Cobb in the episode "Cross Roads".
M1 Carbine
The [M1 Carbine]] is seen used by Henry Jones throughout the series and several soldiers in Okinawa in a video.
M1A1 Carbine
Originally issued to non-combat personnel or those who needed a compact weapon, the M1 Carbine was never meant to be a front-line weapon, never the less it was ideal for Airborne troops for its small frame and it's compactness. The M1A1 Paratrooper Carbine is shown extensively throughout the series most notably in the hands of Donald Malarkey, Carwood Lipton, Warren "Skip" Muck, Lt. Norman Dike, George Luz and Lewis Nixon.
M1903A3 Springfield
A soldier is seen with an M1903A3 Springfield and it's seen clearly when his finger gets shot off.
M1 Garand
Standard issue rifle of the US military during WW2, many of Easy Company's soldiers are shown carrying the M1 as their standard weapon. Most notable is Major Richard (Dick) Winters, Shifty Powers and Joseph Liebgott. Soldiers can be seen using it both with and without a bayonet.
The M9 Bazooka was the standard Anti-Tank rocket for the US military during WW2, excellent against bunkers and buildings though its effectiveness against the more heavily armored German tanks is debatable. General Eisenhower remarked that the atom bomb, jeep, C-47 Sky Train and the Bazooka were the four weapons that won the war. The Bazooka was copied by the Germans as the "Panzerschreck" launcher from a M1 Bazooka captured in North Africa. Generally operated by a two man crew (One Gunner, One Loader) crews quickly figured out that they needed to hit the side, rear or belly armour of armored vehicles, as shown in the episode "Carentan" (The episode also shows how the Bazooka rounds would simply deflect off the heavy frontal armour). The Bazooka makes notable appearances in the series being used by Charles E. "Chuck" Grant in the episode "Replacements" taking out a German Machine Gun and by Harry Welsh in the episode "Carentan" disabling a German StuG IV assault gun.
Browning Automatic Rifle
The B.A.R. was the standard Squad Automatic Weapon for US rifle squads in WW2, It is shown twice in the series being used by an unknown Easy Company soldier in the episodes "Cross Roads" and "The Breaking Point".
M1919A4/A6 .30 Caliber Machine Gun
The standard machine gun during WW2, Korea and into Vietnam. The .30 caliber machine gun is shown extensively in the hands of Easy company being used in both the defensive and offensive roles. It is also shown being mounted on jeeps.
e
Browning M2HB Heavy Machine Gun
The Browning M2HB heavy machine gun can be seen throughout the series. The weapon is usually mounted on either M4 Sherman tanks (as seen in "Carentan") or on the M8 Greyhound Armoured Car as in "Why We Fight". Also making a prominent appearance, especially in "The Last Patrol" is the M51 Quad Mount which, though designed primarily for anti-aircraft use, had a devastating effect on ground targets and was available in either the towed or vehicle mounted versions (designated the M16 Quad Mount).
Grenade
Model 24 Stielhandgranate
Smoke Grenade
M2 Flamethrower
Mauser Karabiner 98k Rifle
Luger P08 pistol
A Standard side arm of German Forces during WW2. It was a prized and coveted souvenir because of its elegant design. Corporal Hoobler kills a German Officer who has one, and then, later in the episode, it discharges in his pocket. It cuts his femoral artery and kills him. It is later given to Sergeant Malarkey, who wanted one to bring home to his little brother. The real gun Hoobler found is a Belgain .32 and was not givin to Malarkey. The Walther P38 was the standard issue during WW2, the luger was just left over from world war one and was still used by some Germans as a sidearm. Also, it was most certainly NOT one of the finest pistols manufactured during WW2 as it was unreliable, difficult to mass produce, and relied on consistent ammunition quality too much.
Walther PP
MP40
Sturmgewehr 44
MG34
Maschinengewehr 42
Adopted by Germany in 1942, in an effort to reduce the machining time and cost inherent in the production of the MG-34, the MG-42 is perhaps the deadliest machinegun used during the war. With a fire rate of 1200 rounds per minute, individual shots are mostly non-discernable. The demoralizing and pschycological effect of its very sound prompted the U.S. to make a training film for troops who would encounter it.
Unlike the MG-34, the MG-42 has a receiver made from a series of stampings, instead of the finely machined components encountered in the MG-34.
The gun is fed from a 50-round belt just as with the MG-34. These belts can be linked together for upwards of 250 continuous rounds from one can, with any number of cans in tow given the situation or position.
The gun is chambered in the 7.92X57 Mauser cartridge, the same cartridge used in the well known K98k infantry rifles, and ammunition is interchangeable, although machinegun ammunition was often slightly more powerful in order to avoid jams and run the guns mechanism more reliably.
It can be used with a fold-up bipod, or with the more complicated Lafette tripod, which could have scope-optics and remote control firing capabilities.
Its downfalls were its high rate of fire, which exhausted ammunition supplies very quickly, and this was very apparent on the Russian front, where the weather often delayed much needed supplies.
It's most effective use (as with most machineguns) was not in sweeping fire but in concentrated direct fire using the shortest burst possible, and directing these bursts over the intended area.
The MG-42 was often seen mounted on an anti-aircraft tripod for use against low altitude aircraft.
In the mini-series, the MG-42 is seen multiple times, being fired from window openings in towns, and in stand-offs with the German armoured vehicles in the advance into France. Most notably, the mini-series did not fail to demonstrate or imply the demoralizing effect of the gun on U.S. troops, and this is a notable achievement for the film-makers, who added this realistic view, which before, had never been seen in such vivid detail in any previous war-film, barring of course, documentaries with actual war-time footage.
