It still remains one of our greatest assets/methods for multi skill testing and development.
FT, as well as itself, can include:
Leadership
Teamwork
Problem solving/task appreciation
Planning/organisation
Communication
Timekeeping
First Aid
Radio
Navigation
Personal Admin/discipline
Resilience
Focus/multitasking
Weapon skills
The extra level of “simulated environment” that FT provides is far more effective at consolidation than practicing each of those in isolation.
That - plus a consideration (regardless of what CAC may or may not want to achieve with some kind of RAF recruit conveyor) that a sizeable portion of cadets who join the forces go elsewhere - will maintain an incredibly strong argument for keeping it regardless.
