Grenade!

70mm figure compared to a 60mm figure by Tim Mee.

He seems ginormous, but really, he is within the normal range of human sizes if the Tim Mee figure is average.

These guys don't have a rifle molded on, but that can be fixed with a little ring hand accessory.

Slip a rifle or carbine sling over his should and he now is fully armed.

It also gives you an additional pose.
