On: A Brief Introduction to Military Pillboxes

[chrononaut]

I can't imagine what it would be like to discharge a firearm without hearing protection in one of those.

[ch4s3 → chrononaut]

Deeply unpleasant, but far superior to the other available defensive fighting positions.

[sobriquet9 → chrononaut]

The muzzle is outside the enclosed space, so I don't think it should be particulatly bad.

[swayvil → sobriquet9]

No eyeball bleeding per se but yes, I predict that you would definitely sustain a significant amount of hearing damage.

My dinky 9mm leaves my ears ringing shooting it just once, without protection, in a grassy field. So I'm drawing from that experience.
