So does the F88. It's not a warstopper.
To expand on my point, I think there is great benefit in developing a course similar to the Ranger Course in the US Army. Most graduates of Ranger School don't go on to join a Ranger unit, they go back to their original unit with the extra skills, leadership, confidence etc to improve those units. It is also an excellent motivator for soldiers.
I would see a similar Australian course aimed at junior leaders (LCPLs, CPLs and LTs mainly) from across all deployable units in the army. You might have, say, a dozen soldiers from an infantry unit do the course each year, half a dozen from a CSS unit or whatever. There'd be a minimum fitness standard, and each unit would only send their best soldiers to attend (ie, a reward to high achievers, beyond simply getting a good PAR).
The course would largely consist of a smash together of a number of existing courses, put in the framework of a demanding environment similar to a special forces reinforcement cycle. You could include elements of the urban ops instructor course, combat fitness leader course, military self defence course, para course, combat first aider course, basic tracker course, dismounted ambush course, Cat C range qual course, marksmanship instructor course, a small arms package to aim at achieving LF18, a TEWT package to improve planning/orders etc etc. Whatever combination of competencies you desire, wrapped in the framework of lots of PT, lots of time in the bush, lots of pressure and responsibility. Call it 10 weeks or so. At the end you get a fancy badge to stick on your uniform, and get to strut around with the confidence that comes with knowing you are good at your job.
Such a course would bring back fit, qualled up junior leaders to their unit, better at their own jobs, but more importantly with the skills to improve the training of the other soldiers in the unit. Give it a few years, and allow the soldiers/officers to be promoted etc, and each unit might have ~10% of their members qualled with a 'Ranger Tab'.
Of course, such a course would be ridiculously expensive, and very, very hard to scrape together qualified instructors for, but I think it has merit. I'd certainly want to do the course.
