Crappers, Latrines, Toilets, shanties, whatever you call that shitty thing.

All the more realistic that they just use the buckets aboard.

I could see countries going to war over being fecal bombed by flying airships.

This is a real life example of exactly what would happen: http://wgntv.com/2015/05/21/airplane-dumps-human-feces-on-girls-sweet-16-party-family-says/

Why the hell would they piss on the chaff box?

[Koali]

They had no idea what it was for, they were just told to toss it out of the plane while flying over enemy territory.

So, naturally, they attempted to add insult to injury.

[ShadedExalt]

Saluted, because hell yeah soldiers

[Kamoba]

Barrels for storage, and a gun to launch them....
The debs didn't want it to be obvious what the gun was so they made the effects look different, however the Minotaur still works well as a disposer of waste....

At least that is what I think since I've heard people call it the "sh*t gun" before

[Koali]

Yup, it does barely any damage. I think the enemy spins away to try and escape the flying [HEUGH]storm you're shooting at it.

[ShadedExalt]

Still breaks guns in one shot, but that's probably more the fact they're covered in crap.

[Kamoba]

I'm not shooting tiis thing till the swabby has cleaned it!

[Sarabelle Marlowe]

urgh, I don't want any stains on my uniform be anything other the coal, soot, oil or blood. I've got standards.

Although, depending on how sealed the barrel was for how long, that methane build up could cause some really interesting results.
