Recently coming out of Baghdad are these images of a very well worn down German STG44 and what comparatively appears to be a less used 9x19mm MP40 submachine gun. There were not any close up photographs of the internals of the small arms so it is hard to ascertain what year in WWII either was made in.
STG44s have been reported in abundance in neighboring Syria, often arming Daesh troops in Raqqa. There is even an inside report on these rifles by a source in Syria from TFB. The largest issue with them is that 7.62x33mm Kurz is extremely hard to come by, although the rifles themselves are very plentiful and in like new condition.
Notice on the MP40 the grip sleeve. These are used on a number of handguns in Iraq and is actually an Airsoft import from China. They come in a number of colors, from green to tan, to black.
