How to arm craft?

How do I arm the HUMVEE, for instance? It queues as "arming" whenever I go into the Equip Craft screen but it doesn't work for some reason.

Humvee doesnt have the same weapons as something like MIG or Kitsune, do you have the right ammo for it ?

Like you need minigun boxes to fill the minigun and there are 2 miniguns, the light minigun and the minigun.
