Looks like a smoke canister found in a supply crate. Emits green smoke, calling an immediate supply drop. One, two or three crates will drop very close to where the smoke signal canister was popped.
If a supply drop crate lands on you it will kill you.
Supply signals can only be found inside of airdrops. They are very difficult to obtain.
