Something ACE had semi developed was the ability to drag/even load ammo boxes
A small ammo box should be draggle by a single person, a medium sized ammo box possibly carryable by two people, larger boxes should be towable via the tow system we will receive at some point later unless it was scrapped.
Loading an ammo box into the back of a truck, helo, etc. should be possible since it has been done in ACE, we've even got PhysX which should help in a couple ways with that.
