Soldier time.

During IFPT you are trained and tested on the skills the RAF and indeed the Ministry of Defence considers vital in the modern field of warfare, besides weapons training you are also taught the basics of general and combat first aid which in real life would help to save a person's life, alongside that you are given the knowledge of how to organise yourselves in the field in terms of what kit to take, how to pack and importantly how to carry it, the last thing you need is a long day on an operation and your backs gone from poor fitting.
