No, even in the military an "assault rifle" is a thing. Specifically, it is a select-fire rifle with a detachable magazine that fires a cartridge of intermediate power.
Assault weapon, on the other hand, is a complete fabrication of the demoncrats' febrile imaginations.
A Kel-Tec SU2000 is just a semi-auto pistol with a stock a and a long barrel.
So, do today's soldiers have to go back to the armory to get their "defense weapons" when defending a position? The military is very specific about what they call things for very specific reasons.
