The 7lbs of kablooey is a shaped charge, but firing it into a steel armor plate means you get a refund, and even a modest refund on that amount puts you solidly in a Ziploc baggie.
There's also that newton guys laws... Which takes the 7 lbs that isn't TNT and hurls it back at you, with way more yeet than it needs to very thoroughly aerate the fuck out of whatever sort of paste like substance the kablooey transmogrified you into...
It would be surprising to me if the operators were the only casualties. Bound to have been a few collaterals, not counting the intended targets. This is a dozen grenades worth of fuckemup, on a fucking pokey stick... The survival rate is a soft chuckle.
I want an alt history where Poland defeats the German invasion in WW2 by making longer versions of these and reviving the winged hussars as an active military unit
Wow that's really cool. Sounds like Mexico honors their folk heros better than we do up here in the US. John Henry only got a Johnny Cash song and probably a statue somewhere.
