And of course in impacts on future VSOs - should you care about them!
If you want your future CAS to be (probably) a 3* by the time he's about 50 (sorry! or she!), if you track back through the ranks, even with not much more than 3 years in each rank, you finish up with a sqn ldr in their (note gender neutral pronoun) early 30s - just about when these guys are currently getting to their first squadron.....
.........but that assumes a future CAS will be a pilot......... (dons flak jacket)
