I concur. I thought every red blooded American Boy grew up making his own (better) fireworks, building muzzleloaders, and joined the Service knowing how to calculate a shaped charge, or whip up a freestyle satchel charge before he got out of AIT, from the toys in hand.
Seems this is 'evil knowledge' only to be known by our betters and our enemies.
If The U.S. is seriously under attack again, I am a volunteer if needed by our military. I swore an oath when I joined the AF. It stands.
