The one on the left is carrying an M1 Carbine and the other might have a Thompson.

 

I noticed that myself, Anon.

During the early stages of the Battle of the Bulge, Hitler ordered Austrian SS commando Otto Skorzeny to assemble an army of impostors for a top-secret mission known as Operation Greif. In a now-famous ruse, Skorzeny outfitted English speaking German soldiers with captured American weapons, jeeps and uniforms and had the men slip behind the U.S. lines and pose as G.I.s. The German pretenders cut communication lines, switched road signs and committed other small acts of sabotage, but they were most successful at spreading confusion and terror. When word got out that German commandos were masquerading as Americans, G.I.s set up checkpoints and began grilling passersby on baseball and American pop culture to confirm their identities. While they succeeded in capturing a few of the Germans, the roadblocks often produced farcical results. Overzealous American soldiers shot out the tires on British Field Marshal Bernard Montgomery’s jeep, and one G.I. even briefly detained General Omar Bradley after he answered that the capital of Illinois was Springfield (the soldier incorrectly believed it was Chicago).

 

I have to respectfully disagree with both of you. The barrel on the left is to fat to be
an M-1 Carbine. I own one and compared it this mornin'. #2 the gun on the right is a MP-40
You can tell by the round front sight, and the Panzerbrigade 150 wore American uniforms
and fought behind the lines, not the front. Sorry guys !

OK, Sarge, you got me on the one on the right. After enlarging it up, the folding stock can be seen poking out underneath his arm, and I see the front sight as well. I still think the one on the left has a Carbine, but I could be wrong there, too.

 

I'm siding with anon on the M1 carbine, Sarge. I owned one back in the 1960's and put lots of rounds down range with it. The one it the picture fits.

If not an M1 carbine what do you think it is, Sarge?

I know lots of Americans used captured MP-40's during the war. They're pretty good a "close-in" work. Only 9mm, but high cycle rate.

 

All I know is my carbine has a front sight post and the barrel is thinner !

 

.... where would he get any ammo for it as the Germans never used any .30 caliber weapons?

Not to belabor the subject, Sarge but I found this on the internet:

Small numbers of captured M1 carbines were used by German forces in World War II, particularly after D-Day. The German designation for captured carbines was Selbstladekarabiner 455(a). The "(a)" came from the country name in German; in this case, Amerika. It was also used by German police and border guards in Bavaria after World War II and into the 1950s. The carbines were stamped according to the branch they were in service with; for instance, those used by the border guard were stamped "Bundesgrenzschutz". Some of these weapons were modified with different sights, finishes, and sometimes new barrels.

TJ, My late wife used to say to me.... Damn it Tim You're so hard headed you would argue with
the Pope. My answer back was who the hell cares. The asshole is always wrong and I'm not a
Catholic. As a former grunt I would never go into combat with a weapon I was not completely
trained on, especially with a limited supply of ammo.
That being said, I still don't think that's an M-1 Carbine and to be quite frank, the subject
is beginning to bore me. Let's move on. You're never gonna change my mind !
