Having been in the military I’ve seen my share of stuff that went out the gate. It’s like a sieve.
Wasn’t in the military but I was DoD directly attached to the US Navy and yes things “grew legs” all the time.
Something like drones however, would have been under tight control at the facility I was assigned.
Even tooling. One incident that occurred was told coming up missing from the central tool room.
The “CTR” consisted of literally thousands of common and special tools.
It didn’t take long until the thief was caught.
I always wanted an 81mm mortar and a truckload of HE and contact fuses.
It's also a good possibility they never left the facility and ten years from now a grunt will open a box and go, "What the hell are these doing here".

Having served in the Navy, civilians would be shocked what certain sailors would sneak off navy ships.
