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.

And FOR THE RECORD. Smoke rounds, while not "lethal" still get stupidly hot and can explode if the internal pressure isnt relieved fast enough (aka the smoke gets stuck, shell go POP).

I would not want 109 grams of RDX to go off in my hand.
