The Bishop is, quite frankly, a ridiculous weapon. Essentially a short-barreled smoothbore version of a cannon designed for frigates and larger littoral class vessels, the combined weight of the barrel and munitions means it can only be fielded by the heaviest mobile platforms, and even them with very limited ammunition.
That being said, the destructive potential of Bishop HE rounds is tremendous, and while I understand the need for such ordinance given the increasing deflective potential of modern shield emitters, this weapon should only be fielded in urban operations if there is no concern for collateral damage. Which is why I find its relatively common deployment on Huss and Canmore units within Solo Nobre extremely disconcerting - the actual firing of these weapons within the walls would inflict calamitous damage.
