I notice each of the toolkits contain these various items. All I seem to have control of is Primary, Secondary, and a Grenade. IE: Rebel Soldier/rifle-primary, pistol-second, grenades-Rt. mouse, where are the dets?
try pressing the "G" button, it should give you your Alt. weapons.
I wish a lot more people used g. Especially anti-vehic units. Their alts are mines, which can shut down armor.
