Sorry utter Military Walt bollox....
I've competitively shot for UK Forces at the highest level and most of this is untrue!
They are trying to show it similar to 'FIB', AKA FIBUA (Fighting In Built Up Areas) and not accurately...Competitive UK Service Rifle FIBUA consists of Standing Supported through a Window, kneeling supported beside a wall and finally standing unsupported...sounds simple but not...tbh top UK trained prefer the Squat to the kneel...Then add various range set ups etc...
Lets not discuss a 500yard Run Down with all 108 lanes at Bisley with multi nationals using various weapons including civvy clubs using military 'Straight Pulls"... Belly, Bum, Stands, whilst supporting a hangover

Then we can chat pistols

Me 2002 Queens Medal Finalist..shooting alongside Booties

Sorry

Pst...old L85A1 having originally trained on L1A1 with A2 not fully issued..
And to be truthful, I wouldn’t have been this good without the knowledge and experience of owning & shooting 'Springers'

Tbh, good days I truly miss...

UPDATE: technique has changed since my day due to the A2/3 (including short tanky version) and added foregrip. With onset of A403A1 aka KS-1...
BUT PRINCIPLES STILL THE SAME
