UKSFs are barely shown their existences to public so lots of rumors talked among people. that reminds me of CAG of US Army.
UKSF and CAG both have another thing in common is that they use their weapons and gears for quite long time. UKSF have used Trijicon TA01 and CAG used EOTECH 551 for many years. they both finally have updated their optics lately.
this time I was pretty shocked to see them fully loaded with almost all gears & weapons which are familiar for long time.
their armors are now First Spear and Crye. and varieties of BDUs! and I had never seen them using M9 before either..
but I feel happy to see that they still use "the" carbine :)
