Organization. A SWAT team up against one homeowner is a non-event. For them. Just wonder though how’d they’d do in woods with someone wearing a ghillie suit armed with a .300WinMag ... or a .22-250 varmint rifle. ‘Course we’re not talking traps and such, that’s extra.
Wouldn't be pretty...
Bingo!
Most civilian SWAT variants are trained in dynamic entry. They might have a couple of snipers trained up to 200 yards or so. Whaddathey gonna do when they are in more open terrain and dozens or hundreds of guys are hitting them from 1-2-4 or more hundred yards, with .50, .308, 30-06, 300 Win mag, 443 Weatherby, 338 Lapua...you get my drift.
They ain’t gonna do so well.
