  Cargo crate that can only be destroyed by heavy class weapons ( turrets, emplaced guns, at-st )  Can spawn useful things when it breaks

MEDPACK - instant use medpacks
SHIELDS - instant shields
BACTA - bacta tanks
BATTERIES -

"health" - how much damage to take before blowing up ( default 25 )
"splashRadius" - damage range when it explodes ( default 96 )
"splashDamage" - damage to do within explode range ( default 1 )
