That phot was taken on a British Type 23 frigate, and I can only assume that they are the embarked boarding team, and are using the ship's weapons, which are never fitted with SUSAT and at present are still A1. Why they are not using, or do not have embarked their own weapons I cannot say.
re SUSAT though I'd always take it preference to Iron sights, you can always use the EBS! Seriously its mostly because I hate the Iron Sights so much but if you must have another reason then there is always getting to and from the target.
No absolute certainty, but as they are practising a boarding on a British ship, and it is the Booties that supply the sharp end of the boarding teams to RN ships, it seems a fair bet. The Booties that we had on for the boarding teams brought their own weapons, which were fitted with SUSAT, and each of them carried a 9mm as well.
Forgive me for venturing entering such a highly expertised area of debate; however, are SUSAT firer's not warned of the danger of "Tunnel Vision" and; merely a supposition find it an innaproppriate tool for CQB? Thany-you....donations to the 'Filbert Fox Fund for Coffee'
Although a dress would show off my exellent legs (might need a shave though) and I look really rugged in a beard.... the thought of me having both at the same time, is just too close to some of the things I've seen in some less reputable drinking establishments around the world to be comfortable. As for being Senior Service? I think RE qualifies on that count
After all, I couldn't be RN. I look shocking in dark blue
Speaking of Sea Cadets, a few years ago when I was involved with the Royal British Legion Festival of Remembrance, the poor unfortunate girl selected to represent and carry the banner of the Sea Cadets had an accident.
As she marched out onto the steps, she was to raise the banner aloft. However, in the dress rehearsal she mistimed it, raised the banner early and speared the 'Exit' sign hanging from the balcony above.
Cue a shower of sparks from the sign, and a shower of abuse from the Garrison Sergeant-Major...
