@Blutze
Despite living in Germany for many years now my German is still abysmal, especially my spelling. Sorry about that. The correct spelling is of course Schützenschnur, thanks for the correction. For some reason my rusty memory seemed to think it was “shootzensnare” phonetically so deferred to Jtam’s spelling. I should have checked it first. Again, apologies.
I agree with your points about the G36. Some fair observations and likely causes.
@JTam I am not surprised at all to see smaller framed people do better on the M4, especially with an adjustable stock. I have seen similar things with folks do better with smaller framed pistols in law enforcement firearms qualifications.
L85... SA80. I have heard folks call it both and I have been trying to remember, without much luck, which was preferred back in the Royal Welch. The design goes way back to the 40‘s.

Training with the Brits was a blast, punctuated with some not so nice stuff. Like getting battered one night in the barracks by four drunk squaddies from another company. I looked like a raccoon for a couple of weeks.
The various accents and the slang can be difficult to navigate for some of us Yanks. Throw in Cymraeg (Welsh) and Gaelic, it can make your head spin.
International cross training is awesome. I miss that. Sounds like you had some great opportunities.
