The obvious difference between military and civilian instruction is the pace of learning. In the civil world this is usually dictated by how fat your wallet is (or was), in the military the pace is deliberately fast to identify the weaker candidates as early as possible. As my very first QHI said after a particularly poor exercise, "I could teach your granny to fly this helicopter if I had a year, but you've only got the next hour to buck up or find a new career".
