When you equip disposable weapons to a battle armor with an AP mount, does that function as a normal disposable weapon (in that it supplements rather than replaces the normal primary weapon) or does it replace the auto-rifle or whatever that would normally be placed in an AP mount? What about for BA with armored gloves, do they carry both the primary weapon and the disposable, or just the disposable?
Also, does carrying a disposable weapon with a crew of 1E encumber conventional infantry the same way using it as a secondary weapon would?
