is it possible to have both the heli and bradley drop crates for people who do over 40% of the damage

drop additional crates? I could add that, but your question is not clear

lets say you and i are both shooting at the heli or brad and we both do over 40% damage can the heli or brad drop each of us crates that are instanced to us

it's still confusing. are you locking bradley and heli to these players? are they on the same team? should they be?
