It’s just two breaching rounds. It’d work as well with a pump, because of the ease of loading with two specialty rounds. Bang, pump, bang, drop, draw, enter.
The M3 (selective-fire M2 with IR scope) was not released until much later. The M2 was not released until ‘44. Most tankers were issued, whether officially or not, plain ol’ M1 carbines, my personal favorite firearm. I especially want one made by the jukebox company, Rock-Ola, which used to be just up the street.
"Alright you Primitive Screwheads, listen up! You see this? This… is my boomstick! The twelve-gauge double-barreled Remington. S-Mart’s top of the line. You can find this in the sporting goods department. That’s right, this sweet baby was made in Grand Rapids, Michigan. Retails for about a hundred and nine, ninety five. It’s got a walnut stock, cobalt blue steel, and a hair trigger. That’s right. Shop smart. Shop S-Mart. You got that? "
In answer to the OP: a double barrelled shotgun would be the preferred weapon where you are confronting something that moves extremely quickly, where there is only likely to be one of whatever-it-is, and where it is really, really important that you hit it as soon as possible. Say, a flying creature with a poisionous bite.
The Other Waldo Pepper, I don’t see anything in that scenario that prefers a double barreled shotgun over, say, a semi-auto. First shot, the second round is chambered before the gun is aimed at the second hinge. Don’t see how a DB is faster.
No doubt I’d take a DB if that were the shotgun available, but if I’ve got pref, why should I want a DB over a semi-auto or auto and a dozen mags?

It’s the only way to be sure.

Why would a DB be preferred over a pump action or semi-auto or combat auto? I can see why it would be acceptable, but why preferred? Also, said critter probably shouldn’t be very large. A dragon with thick scaly hide might be able to take even buckshot without much damage. At least until close up.
The same reason having a double-barrel may be preferred for hunting ducks: easy to get two shots off within a split-second when something is moving very, very fast, by having a finger on the trigger ready rather than waiting that split-second for a shot to chamber and pulling the trigger again.
Mind you I confess I’ve never shot a “combat auto” shotgun.
I admit that in the vast majority of combat situations, having more than two shots before reloading is much more significant an advantage.
