Is that a Thompson M4?
This great picture popped up on MilMag, a Polish firearm magazine, showing a group of U.S. Army Soldiers milling about, digging the heat somewhere sand-colored.
On a closer look, one, a Spc. Lord, has what looks like a dead ringer for a Thompson M1921/28 submachine gun foregrip affixed to his M4 handguard, like a baller.
Some reverse image searching (thanks for not listing anything about the photo, Mil Mag!) found that the group was from the Tomahawks of the 2nd Battalion, 23rd Infantry Regiment, 4th SBCT, 2ID as they were operating in in Takhteh Pol district, Kandahar province, Afghanistan. The photo was taken 05.02.2013 by Staff Sgt. Shane Hamann with the 102nd Public Affairs Det.
In search of more images of Spc. Lord’s epic Tommy gun M4, it was no joy. A follow-up image by Hamann took three weeks later showing the specialist involved in personnel searches at a traffic control point in Panjwai district, shows him with a more traditional forward grip.
Sigh. I bet it was magnificent while it lasted.
