For a good read & plenty of reasons why we should not be wasting our hard earned taxes on Typhoons, JSF, A400M's, antiquated Nimrods, aircraft carriers,etc., buy a copy of "Lions, Donkeys & Dinosaurs" by Lewis Page-ISBN: 978-0-09-948442-4.
Then write to your MP, ineffectual though he/she is to seek the sacking of the MOD procurement branch & the equally ineffectual Service Chiefs.
After that, start pushing for a Combined Defence Force on Israeli lines & get rid of the majority of the upper tiers of moribund Senior Staff Officers along with their inflated salaries/pensions etc.
When you've done that, recruit more "grunts", give them a decent wage, decent boots, body armour, & a new rifle which works every year!
