When I mean Semi-Auto rifle I mean something like the M4. I wasn't sure if Assault Rifle was a correct term.

>For the attackers, would it make sense if they were armed with shotguns, or should they stick to semi-automatics or even SMG's?
SMGs would be best. At trench ranges, shotguns simply dont spread much, not enough to justify their shallow magazines and limitingly large ammunition.

I'd also like to know about the effectivenss of the AA12 vs the M4 when deployed en masse in a trench warfare scenario too.

Ah, I see.

How about the Defenders? Is it best if they just stick to their M4s if that's their standard rifle?

Also how about Fully Autoshotguns like >>34099892

Bump, I'd like to know this too. Would trench warfare be very different if everyone had M4s instead of the bolt actions they had in ww1?

how about pic related?

>>34099887
Also i take it that even drum mags for shotguns are considered "shallow" magazines?

Is it summer already?

Why would you swap a weapon that holds between 2 and 5 times the ammo, can be reloaded faster, has smaller lighter bullets that you can carry more of, AND can engage targets effectively at several hundred meters for a shotgun in that situation?

Mostly because I was wondering if the effect of being hit by a shotgun blast is more effective at stopping someone at very close ranges than an M4, particularly in the case where they've practically closed the gap and are right on top of the trenches.

>In 1900, during the Philippine Insurrection, Captain John Pershing saw combat against the Juramentados, fanatical Islamic Moro swordsmen who sought martyrdom while killing their enemies. The Army Colt .38 didn't stop their suicidal attacks and even the Springfield rifle didn't always do the job. In such close quarter fighting, the Model 97 Riot Gun, a pump-action shotgun, usually gave the Juramentados their desired martyrdom.

In this case a line of soldiers in a trench is at risk of being overrun by a large mass of men, having already engaged them at range with M4's, if its just best they stick to the M4's they have already or if it makes any sense switch to something like pic related.

I had envisioned that a 12 guage shotgun blast would have a lot easier time making a person drop dead at close ranges than a hit by an m4, but if that's not true then that's all I really wanted to know.

Missquote.

>When soldiers equipped with Model 97 Trench Guns jumped into an enemy trench, they were able to clear it quickly in both directions using the slamfire mode. The relatively short barrel length allowed them to quickly swing in either direction in the narrow, confines of the trench. In a matter of seconds, 54 8.4 mm balls of buckshot with an effective range of up to 50 yards tore up anyone in the way. Such firepower, restricted to close-in fighting, had a greater hit probability than any available automatic weapons of the time. They became known as trench brooms or trench sweepers.

Why not have both, get a semi 12 gauge with a 10m long magazine tube and load it with slugs.

Probably not, the vast majority of casualties (75%+) were caused by artillery. Sure it would help for trench clearing, but even then dedicated trench clearing units a la sturmtruppen usually only carried a pistol at most, and just sacks and sacks of grenades; later on smgs were used to good effect as were shotguns, but at that point its because anything is better than a long bolt action rifle.
