Operation Diadem, Italy Soldier holding a destroyed military helmet during the Operation Diadem on World War II, Italy, May 1944 The LIFE Picture Collection   Note the 13 in square on helmet.  Documented examples are posted here on the forum.     

I would agree to the assertion that all of these men were part of Company G, 112th Inf Reg, 28th Inf Div as I found Eddie Patton (1918-1978), George Penny (1912-1980), and Joe L. Tanner (1925-1997) listed in a 1945 Document (awarded the GCM) attached below. I have hyperlinked the above veterans with their findagrave pages as well.   Furthermore, we can actually semi-date this piece to when it was signed as Stanley E. Babiak (1917-1991), per his WWII vet compensation application, was only overseas from April 16, 1945 to  August 3, 1945. This record has also been attached.   Hope this helps!

This is a late WW2 production M1C but used in the KW.

Just to add some background info about the real-world engine: The T700 turboshaft engine is widely used in both military and civilian helicopters. On the military side, it's found in the Sikorsky UH-60 Black Hawk, SH-60 Seahawk, McDonnell Douglas AH-64 Apache, and Bell AH-1W SuperCobra. In civilian aviation, it powers helicopters like the Bell 214ST and Sikorsky S-70C. There's also a turboprop version of this engine, the CT7, which is used in commuter aircraft such as the Saab 340 and CASA/IPTN CN-235. Thought this might be helpful for anyone interested in the technical background behind the model.

The blade looks like a heavily modified Ka-Bar blade, I definitely think theater made. that’s a pretty cool knife honestly. The guard also looks very thick so maybe it’s made from a damaged one and they took off the guard and redid the leather washers. Can’t really tell if the Riccaso is different. But looks good. Not a knife guy so just my .02

GWOT era Modified Tru-Spec green tiger set.  Even though this set was from the US, it was modified in Afghanistan as evidenced by the elastic loop on the sleeve pocket.     Modified green and desert tigers were used by SF/SOF/OGA types.  Judging as to what came with this grouping, I believe these were used by a SF/SOF/OGA advisor to the Afghan National Directorate of Security (NDS) militias,
