I need one of those for squirrels and such.
Every Shooting range should have one!
Ammunition supply comes to mind. A couple of questions come to mind.
Although you can get better penetration out of a 57 mm round and longer engagement ranges ballistically, how likely is an such an infantry fighting vehicle to engage at ranges beyond the effective range of a 30 mm round?
Is the terrain smooth enough to allow those engagements or is it broken up enough to negate the range advantage due to lack of line of sight to target?
