Not just the Army. The Royal Navy also completely overhauled and increased the standards for operational evaluations and work ups by the Sea Riders. They became a lot more difficult and much more realistic. They had been cruising throughout the Cold War with the lessons of WWII, never having given much thought to the weapons, weapons systems and sensors developments of the previous 25 years.
They were not the only ones. All of this type of training was greatly increased in most NATO navies as a result of the RN's lessons learned.
The physical fitness triumphs of the Airborne and Commando units (including their attached arms and services who all completed the same selection courses) were countered with the massive fitness failures of the Guards regiment battalions, as well as many attached arms and services. So there was a desperate attempt to rapidly increase 'load carrying fitness' of a chubby, mainly BAOR/Armoured warfare focused army as a priority.
In the Army the fitness standards skyrocketed almost overnight and, in addition to the 'Battle Fitness Test' (1.5 miles in 12 minutes wearing boots, 9 minutes for PARA) these two additional tests were introduced:
- 2 mile Infantry Combat Fitness Test (ICFT): 35lbs webbing, rifle, 2 miles in 18 minutes, and
- 8 mile Combat Fitness Test (CFT): 35lbs webbing, rifle, 8 miles in 1 hour 35 minutes
Infantry, and atts, had to pass all three tests annually. Combat Arms units had to do the BFT and the CFT, and many also did the ICFT too. I once helped out with running a CFT for the Army Catering Corps depot and was hugely impressed by how well all those combat cooks did!
P Company, the Parachute Regiment's selection, got harder IMHO as they borrowed from WW2 fitness requirements, and events in the Welsh mountains - like the dreaded 20 miler - were reintroduced.
It was also a shock to alot of people when formerly attendance only 'gentlemen's courses' featured a CFT in addition to a renewed, ruthless focus on performance. I recall one FTX on the Pl Comd's Battle Course featuring a grueling, Goose Green inspired, 7-8 hour 'on your belly' Coy Gp level fight through, for example.
Fortunately Sandhurst (Officer training for all arms and services in the Army) already had a huge focus on battle fitness, even before the Falklands, and our CAF Combat Training Centre (at the time) had nothing to compare with it. Log races, timed battle marches, ruthless APTC led gym sessions, assault courses, and long range events through the Welsh mountains were all SOP.
However, they increased the length of Sandhurst from 6 to 9 months and included alot of 'character building' activities too, like challenging adventure training modules, and a long range (30-40 mile I think) romp through the Welsh mountains resembling the Cambrian March, to help build greater resilience and confidence in young leaders.
Similar upgrades were made to the Infantry Section Commanders Course, and the Pl Sgts Battle Course, in Wales.
So, yeah, the British had alot to thank the Argies for in terms of upping their 'training for war' game...
