Well, I guess they are used very well, because:
-No A3MP and no Isla Duala parts mean that N'Ziwasogo does not work
-SP pack is a requirement for US pack and provides the OD single color uniforms of the opposing forces
-US pack provides the M81 woodland camo of US forces
-NATO SF and Russian weapons pack provides a small selection of "free world assault rifles" and AK's for the enemy
-I think Massi updated his weapons pack just recently, so please try without the audio fix
