INFANTRY THROW WHILE SNEAKING
This is interesting because it means inf won't wait to come to a stop before throwing a grenade (yellow line below)
Also notice the long 38 metres range which is pretty good although the furthest I've ever seen infantry throw a grenade is 40 m.
(But they'll only throw heavier stuff like gren-bundles out to around 30 metres or so)
PS - The Panther was killed when the grenade hit, normally it'd take more than one to kill a Panther but it'd taken crew casualties earlier so they were shaky and quick to abandon)
