A letter from a US Army Major

[PPCLI Guy]

Met a 35 year old British RSM.  Those guys were saying if someone doesn't reach a certain rank by a certain age they get switched over to some non combat type admin  job.

As I recall it, you can do a maximum of 22 years as an OR in the British Army.  Those RSMs that stay on do so as "LE's" - ie CFRs.
