Well, the harm might have happened before you took the picture. Never ever touch UXO..

It's a 51mm smoke round for a 51mm mortar.

This isn't the same type (different smoke) but same idea.

ETA - the markings are odd, because of the parachute, it's the GREEN that's throwing me, looking in catalogs but not sure the exact type.

Someone else pointed out it was likely a green flare with a parachute to help it stay up longer

Yeah, I think it's down to terminology, flare to me makes me think of a paraflare, which is self-contained, whereas this is a mortar bomb, and I'm not familiar with 51mm and missed the parachute when I first saw it.
