and a tank is just going to let you walk up to it and roll something down its barrel? Or will it mow you down with a .50 or .308?
Why are they shouting for Admiral Ackbar?
Here's a potentially ignorant question...if you didn't have a grenade and just forced two or three feet of thick chain down a tank barrel, would that confound the round's exit enough to Kb it, Glock style?
Yes it would. A tube sock full of mud and rocks pushed in a foot or two would accomplish the same thing.
All you need is something that will stay in the barrel long enough for pressure in the chamber to expand beyond what the chamber was designed to handle.That seems hard to believe. Wouldn't you need something that would truly wedge itself in the barrel? I could see attempting such a thing as sabotage while the tank is unmanned, but to be on the business end of a tank barrel fiddling around like MacGyver sounds like a good way to come up short an arm... or head. And that's assuming it isn't manned by a gunner.
