I recently installed the 1.08 update for Armed Assault (1.05->1.08) and now i'm having problems with the game. First of all, the soldiers rifles are non-existent. There is no model, and they use the idle animations, or if they have a pistol, they will fire the rifle rounds from their pistol. The supposedly unarmed soldiers can fire rifle rounds from their crotches. The pilots and other soldiers with pistols fire the rifles from their pistols, if that makes sense. The weapon is changed from pistol to rifle by pressing the 'change firemode' key. The pistol still remains in the soldiers hand, however. The second problem is that machinegunners and automatic riflemen cause the game to crash.
It's due to some addons you've installed conflicting with some of the weapon classes. Remove your addons then add them one-by one to see which ones are causing problems.
Most of the addons that used to cause this problem such as Mechastalin's BMD and some of Vilas' addons have now been updated to work post 1.08, so you may want to make sure you have the latest versions of these too.
Yep, getting rid of my addons fixed it. Thanks.
