The Desert Eagle Mark XIX is available in the game. Although depicted as the .357 Magnum model, shown by the use of .357 ammunition boxes and a 9-round magazine, the weapon model is actually that of the .50 AE variant, as evidenced by the lack of a fluted barrel.
A suppressed Heckler & Koch MP5 is commonly available as a starting weapon. Despite being referred to as "Mp5 SD3" in-game, it is actually modeled after an MP5A3 with an original "slimline" handguard and a non-integral suppressor. The alternate fire button allows for an increased zoom, even though there isn't any sort of scope present on the weapon. It has an overloaded 32-round capacity, which in reality would make reloading difficult.
The Uzi commonly appears in enemy hands; a dual-wielded version can be found as well. It has a much higher rate of fire than an actual Uzi, at 900 RPM (close to that of the Mini Uzi variant) versus the real 600.
The Pancor Jackhammer can be found in the game (unrealistic, seeing as only two full-auto prototypes were ever made), with an incorrect 12-round cylinder instead of 10.
A loading screen shows Jones aiming a Colt M16 fitted with A2 handguards and an M203 grenade launcher. It is not used during gameplay though; the XM177E2 mentioned below is used instead.
The "M16 A2" in the game is actually a Colt XM177E2 with an M16-style stock; it is equipped with an M203 grenade launcher. It fires fully-automatically, correct for the XM177E2, but incorrect for the M16A2, which fires in 3-round burst mode in reality. It also only carries 20 rounds per magazine, despite being modeled with 30-round magazines
The first-person model of the "AK-47" in the game is actually that of a Zastava M70B1, but modeled with the full-circle front sight of a Norinco Type 56. It is the most commonly found weapon in the hands of enemies. It has an incorrect 32-round magazine instead of 30, and is modeled with the charging handle, ejection port, and selector on the left side.
The Dragunov in-game is actually a hybrid of the SVD Dragunov and the Romanian FPK/PSL. The weapon is silenced in-game, despite the model not featuring a suppressor visually.
The LAW 80 often appears when the player is tasked with destroying enemy tanks. At some point in the game, three LAW 80s can be found in the same level, in which case the weapon will be able to fire the three rockets in a semi-automatic fashion. This is obviously incorrect, as the real LAW 80 is single-shot and disposable.
The M203 grenade launcher is attached to the Colt XM177E2. It is incorrectly reloaded by pumping it instead of opening the tube, loading a round and closing it.
