Commandos: Behind Enemy Lines
Commandos: Behind Enemy Lines is a single-player real-time tactics video game developed by Pyro Studios and published by Eidos Interactive in 1998. Beyond the Call of Duty is its stand-alone expansion, released a year later by the same developer and publisher. The expansion added new weapons, mission and enemies.
The following weapons can be seen in the game Commandos: Behind Enemy Lines and its expansion Beyond the Call of Duty:
Smith & Wesson 4506
The Smith & Wesson 4506 with wooden grips is the pistol of choice of the Commando team. This is the only weapon that can be used by the whole team (the only exception being the Dutch Contact, a character added in the expansion). Three shots can bring down an enemy soldier. Has a short range, comes with unlimited ammunition and fires as fast as one can click the mouse button. Appears as "Gun" in Behind Enemy Lines, and as "Pistol" in Beyond the Call of Duty. The weapon is heavily anachronistic, considering that the game takes place in the second World War, but the S&W 4506 was produced from 1988.
M3 Grease Gun
The Grease Gun appears as "Submachine Gun" in the game. Only the Driver can use it of the Commandos. Has a small range and is always fired in short bursts. Usually 10 or 20 shots can be fired from it before it runs out of ammo.
The Sapper's standard fragmentation grenade is the Mills Bomb.
Duke's Sniper Rifle
Probably a Springfield variant, it is impossible to tell because only the scope can be seen in the inventory menu. Each hit grants instant kill. The remaining bullets are shown in the backpack.
The Beretta M1934 wtih wooden grips is the standard handgun of Lips, the Dutch Contact in Beyond the Call of Duty. Has unlimited ammunition. Appears only in the "Dangerous Friendships" mission.
The Driver's new weapon in Beyond the Call of Duty is a Lee-Enfield rifle. Only part of it can be seen, so it is impossibly to determine the exact variant. Appears as "Rifle", and has limited ammunition.
Not Usable Weapons
In Beyond the Call of Duty, a picture of a M1911A1 can be seen after each completed mission. On the photo of the developers shown during the credits, two Pyro Studios employees are seen with (possibly non-firing replica or airsoft) M1911A1 pistols.
M1 Garands are seen during the cutscenes of the original game.
An M1928A1 Thompson are seen during a cutscene.
MP40s are seen during a cutscene in German hands.
The MG34 machine gun is seen in the hull mount of the Panzer III and Panzer IV medium tanks.
Various Generic Weapons
Unfortunately the weapons the German troops use during the missions are not detailed enough to determine the exact variants. Here is what's certain: German officers are always using a pistol (probably Luger P08 or a Walther variant) in the game. Most of the Wehrmacht guards are armed with rifles, possibly Kar98k's. The Machine Gunner soldier are using what appear to be the MP40. Several emplaced machine guns can also be seen, probably MG42s or MG34s.
Several Flak 38 anti-aircraft guns can be seen throughout the original game, as well as in the expansion. The Flak's usually represent objectives that must be destroyed in order to complete the given mission.
See Mines are seen during the first mission of Beyond the Call of Duty called "Dying Light".
