First Great Mod... Long time lurker.
Not sure if they had been mentioned yet but here they go...
1. Guard smoke nade hot key is "R" which is the reinforce hot key.
2. Not sure if bug or feature, ambush for sharpshooter team only cloaks the sniper
3. again not sure if bug, Heat rounds on at guns are 150 munitions, seems extremely high being that you also have to research it.
4. Just an observation but I might be wrong, seems as if tank hunters don't do alot of damage for a handheld at weapon.
thanks for the mod its really well done.
