Biden: *checks watch* we need to regulate assault weapons in the U.S. so they don't fall into the hands of dangerous people. *licks ice cream*
Taliban: *releases ISIS from prison*. Thanks for giving us literally thousands of actual assault rifles! We'll keep good care of them for you while we plan our next attack on you. *bombs our service personnel*
Biden: *sniffs children* That was Trump's fault. *falls asleep*
Hesco plates- you probably don't need lvl4 so save eight with 3610's, ect.
HRT makes a decent plate carrier. No plate carrier with decent ceramic plates is going to be 'low profile' or 'concealable,' you'll be open carrying half your armory like a proud autist anyway. Get something made out of cordura, with the buckle system, and some decent padding.
Helmet- ACH if you must.
Consider if you're in good enough shape to move more than a few miles in all that shit. A chest or belt rig is more practical for light infantry field ops, imo
