Seems like body armor and a good helmet would be decent defense against this thing. Also it might force defenders to put some kind of roof over their heads. It could be very useful out in a field but I wonder what kind of use this gun has in an urban environment that wouldn't be better suited for a traditional grenade launcher or shoulder-mounted rocket.
I wonder what the rate of fire on that gun is.
Urban environment? The thing shoots through windows and light wooden doors. Even if it didn't make it through the door the first time, you put the second round through the hole. That would go for most buildings. Anti-personnel isn't the only round developed for this system, IIRC.
The Barrett M-82 has a few different rounds developed for it. More specifically the .50 cal system has different rounds developed for it. One is called a Raufoss. It has an armor piercing tip with an explosive anti-material section behind it. Shoot through the wall, it explodes, makes several helpings of Hamburger Helper. You can do the same with the 25 mm round as well, provided it has the kinetic power to punch through the wall.
Secondarily, it technically can shoot around corners. If the target is defilade behind the corner of the building, you set the round for 1 meter past it. Basically you're taking the overhead kill shot behind an obstruction and turning it 90 degrees on the side. Exact same concept.
Body armor and the helmet only cover the body's core and cranial areas. They are heavy units, I think the US military's most common issued elements weigh in at around 35 pounds. And they are not cheap. That still leaves the arms, legs, neck and sides of the torso exposed, and considering the round is fragmentary, there are parts and pieces of steel flying all over the place looking to make a bit of trauma.
Unless you're hiding in the refrigerator from the last Indiana Jones movie, this round can find you and make a bad day go to a downright ***** one.
