Field Guns, anyone?

the M119. shorter range but VERY versatile.

"Little David" 914 mm mortar

Dardanelles Gun. Almost 4 centuries of European crushing fun.

I am pretty sure that is a British QF_17pdr (76.2mm) Anti-Tank Gun, the only gun of the western allies that could take out a Tiger Tank at long range

As for my favorite, always liked the British QF-25pdr (84.6mm). It was supplies with a circular firing platform that meant that it could fire in any direction.
