Seen in the historical flashback sequence at the beginning of the film, many rifle are seen from a distance, but it is hard to identify them since the battle is at night and the only time we see long rifles, the soldier holding them is being blown up by cannon fire.
FN MAG
FN MAG-58 Machine guns are seen mounted on trucks and boats, all manned by Kazims' troops.
Browning Hi-Power
Seen in the hands of Kazims' Troops and later commandeered by Dirk Pitt (Matthew McConaughey).
Walther PPK
Dropped by Al Giordino (Steve Zahn) when he is disarming himself when confronted by the Tuareg.
When Kazim's troops are mobilizing, three soldiers walk by carrying 12 gauge pump shotguns, of a yet undetermined make and model.
Note - I just saw this scene on the television but can't find it on the DVD. It may be an extra scene edited in for the broadcast... MPM2008
Norinco Type 56-1
The under-folding stock version of the AKS-47, made in China is seen throughout the film. Mostly a mix with other AK types, carried by Kazims' Troops.
Colt M4
The only time an M16 variant is seen is in the hands of one of Kazim's soldiers, riding in the pickup truck that takes a handcuffed Dirk Pitt and Al Giordino across the desert.
AK-47
One of Tuareg fighters who help Pitt and Giordino raid the waste plant carries what appears to be an original milled receiver AK-47 - (7.62x39mm).
AKM
Mixed in amongst the AK-47 rifles are AKMs, many of which are modified with 'tribal' decorations.
M20 Super Bazooka
Carried by Tuareg tribesmen in the desert battle - 3.5" Rocket.
Yves Massarde (Lambert Wilson) gives a matched pair of French Flintlock pistols to General Kazim (Lennie James) at his palace. They are a duelling set with silver caps at the bottom of the grips and have other inlaid silver accents. It is mentioned that they were formerly the property of "General Mayenne" causing Kazim to quip that they must have killed 'The Comte de Vézelay' (French for The Count of Vézelay, in the Bourgogne region of France. Though there is no famous Count from that area, it is most known for holding the abbey where the bones of Mary Magdalene were brought.)
General Kazim (Lennie James) uses his ".455 caliber" Smith & Wesson New Model No. 3 revolver to shoot (W.H.O.) Doctor Frank Hopper (Glynn Turman), Eva Roja's boss, with it. It is a Silver Smith & Wesson New Model No. 3 with ornate engraving all over the pistol. Kazim mentions that the pistol was previously owned by "General Sir Henry Watkins" and that he must purchase custom loaded ammunition from Holland & Holland of England since the .455 rounds are so rare.
Type 69 Rocket Launcher
Some of the Tuareg carry Chinese Type 69 RPGs though they have different warheads
Carried by General Zateb Kazims' armored troops at the final battle (in addition to the plethora of AK47 type rifles). They look to be the solid Metric style front sight block, however the barrels seem shorter than usual, so the exact model is unknown, but they appear to be Metric FALs - 7.62x51mm.
Seen mounted on the tanks used by Kazim's Armored troops.
Romanian WASR-3
I believe that Al's rifle during a desert battle is a Romanian WASR-3 Rifle built at the S.C. Uzinele Mecanice Cugir S.A. (Cugir Factory) in Romania. The weapon probably came from a foreign armory, but for the purposes of identification, the U.S. version of the Romanian .223 AK will be identified. The Romanians imported a series of three AK type rifles called the SAR series.
The SAR-1 was 7.62x39mm, the SAR-2 was 5.45x39mm and the SAR-3 was the 5.56x45mm. Then a later variant was imported, the WASR. The WASR was essentially the same firearm, but with a lower grade of fit and finish. (The original WASRs were imported to take only single stack magazines (to please BATF) and the wholesalers opened up the mag well to take standard magazines and replaced some of the parts with U.S. Made parts to make them legal). Like the SAR series, the WASR-1 was 7.62x39, the WASR-2 was 5.45x39mm and the WASR-3 was 5.56x45mm. However, the SAR-3 rifle has the original AK74 style gas block, the WASR-3 has a modified AKM style gas block and blonde wood. Both the SAR-3 and the WASR-3 take the ROMAK 223 magazine (Wieger style). This rifle is set up with the Wieger style magazine. Al Giordino's rifle is a WASR-3 (or the European equivalent) and of course, his is fully automatic. It looks to be the same rifle used in the movie Casino Royale since the Sascha Robey was the armorer for both movies.
