Can the BMP-2 hide in rooms?
Of course it can.
You're basically saying infantry firepower shouldn't be improved because IFVs will always have larger guns.
Even with an exoskeleton a soldier wont be bullet proof, so a 14.5mm AR is simply not necessary.
It would make rather more sense to give that soldier a laser target marker and use it to guide bombs from orbiting Bears, Backfires, and Blackjacks.
I meant that now ratnikand AK-12 are only given to spetsnaz, delaying their delivery to regulars.
I dare say spetsnaz have had it for quite some time and this is a roll out to the Ground forces.
