Odds are if you are dirt poor Republican you are much more likely to be shuffled into a sweatshop to sew socks than take advantage of anything that’s going on here.
Cheap socks imported from China are 148% more expensive, you’re still nowhere near having the capital to own a single thing in your life, the rich are only going to get richer, and those socks ain’t going to make themselves
My very armchair general-ish educated guess:
If they have an HE round loaded, a shot might damage or activate the shell’s very sensitive front facing fuse, causing it to immediately explode and also cause any other readied shells near the loader to explode, virtually guaranteeing the tank crew’s death.
Other shell types, they have thick and inert ballistic cap that is propelled with enough velocity to shred armor. Basically an oversized bullet themselves. A pistol round would not go through the ballistic cap, only crumple and deform it. But there may be a chance it would make the shell misfire and damage the barrel when the tank crew attempts to fire.
