[HELP] Model/Object Spawning Yes/no?

i heard that i will need a gsc for spawning random objects such as;

~ uav (plane itself)
~ attack chopper (plane itself)
~ Hive (plane itself)
~ Chopper gunner (plane itself)

is this true?..
and no i am not asking for someone to create a gsc script etc. just a yes or no with a "why not"

i need it as i cbf waiting for bots/mp[enemies] to obtain these killstreaks. texture modification wise.

thank you for your time.
