..and the SAS just use basic drills..done as close to perfect as possible..until the movement can be carried out perfectly under the most extreme conditions..
..and the same applies to learning each boxing technique..
..practise doesn't make perfect..perfect pratice makes perfect..that's one SAS sayin' or quote....
..i think Bruce Lee quotes somewhere that you only use what you practise..so never abandon practicing your basics..ya bread and butter..
