Ocean mine.

Many sea mines of that era are actually activated by disturbances in magnetism! They’re pretty good about not going off unless something large and metal rolls up, since that’s their purpose, although anything really old is suspect of not working as designed. That’s why when somebody digs up (or just kind of has) an old bomb they detonate it on site instead of trying to move it.

WWII also saw acoustic mines used. Contact mines were and are around too, and I would guess if you don’t crush a trigger the same answer about only going off when conditions are met applies.

Modern low-sensitivity explosives can survive an actual plane crash without going off, and will burn instead.

helmet (why not just move the whole sentence into the text, OP?)

SSTF covered everything from here on pretty much perfectly.

On the off chance your helmet does successfully take that kind of punishment, and the blast wave is absorbed enough to not hurt the soldier, there still will be a bunch of hot gases escaping in every direction which isn’t great. Better than no helmet, though - the trick is just noticing the grenade, stopping, removing your helmet and gently placing it over top before it blows up, which is why that move isn’t actually a thing.

TBF, something’s already gone funny if you’re finding pipe bombs on the street.

Roman Emperor Claudius, so the story goes. If it did happen, it might have been for show rather than because it was really practical for warfare.

No, Claudius actually boated them over to scare the locals into shape. Or reputedly so.

It’d be pretty easy to guess, honestly. Just saying “a lot like a cow, with legs like in the front” would cover it for sculptural purposes - the flattish tail being an excusable detail.

Medieval artists did a lot of this, although sometimes the results were less than perfect:

Yep.

Although any reasonably large cargo boat should be able to carry an elephant, anyway. That would be how the Romans did it in Britain.

Edit: Maybe? Apparently the only source on that episode is from much later.

And AK, for that matter.

Man, Nigeria better be careful.

The bottom text and rule 4, sure. The rest is questionable.

It needs to have stuff about marksmanship, the larger mission, concealment and surprise ect.

Okay, but they definitely didn’t come into a place that was fine and make a mess.

(And if something is wrong, and you can intervene, you should. It doesn’t matter who you are; that’s just morality)

Ah yes, post-breakup Yugoslavia and Libya, famously places where everything was great there was no violence until the West showed up.

Iraq is a more legit example, since that was under false pretences, but like the other user noted most of NATO refused.

It’s Putin fans, so they’re probably saying NATO = homogay, and that’s bad.
