25mm huh? I hope we can get one into the hands of every rifle company out there. That is some serious firepower. That puppy would do to concrete walls what the .50 cal "God" was carrying in US Navy SEALs did!
It would be nice to have something like that on the infantry level. Sure, they have the Bushmaster 25mm cannon on the Bradley, but this thing can be more versatile since it can be carried, set up and used by light infantry while dismounted.
Such a weapon would have to have some serious punch and range. Imagine a sniper on a roof overlooking a town with one of those things! And if cover is an issue, that weapon will make it a non-issue. Hell, even if the bullet doesn't make a direct hit in the target, an HE round going through walls and vehicles would have to generate lots of secondary missiles that could cause the badguys to have a bad day.
