People join the military (not just the army) for 101 reasons. There are so many different trades across all 3 services it is not as simple as "soldier" "pilot" or "sailor".
Agree with this statement I know Doctors/Mechanics/Office Managers/Nurses/Drivers who all work for the army. Then of course you have the other forces. They all have several reasons why they joined up - some before 9/11 some after. All are valid. They are men/women, DW's/DH's, expectant parents/parents/grandparents. They are just like everybody that you walk past in the high street - you wouldn't know unless they were in uniform. They could have the same job in the civillian world. However they get long leave periods, extra training, opportunities that you might not in civillian life - sports/travel/a chance to branch out - and job security. Yes they risk their life and as threads like these show people think that they are dead beats with no other life/job chances, are thick, think that they have joined up to kill and aren't proud of our forces personell.
I am proud to be part of a country where we don't have the taliban governing us or be worried that women will be kidnapped/killed, that our children aren't given a gun at the age of 6 to fight etc - instead we help these countries we teach their men how to govern their country, we teach their soldiers, we treat civillians in their hospitals not because we have blown them up but because we have skills we can teach we can bring over supplies we help build infrastructure, we help get rid of unexploded land mines, we hopefully make life easier so that we can hand back their country to them and they can cope.
I speak to the soldiers that go out there/who've been out there and they're scared - but it's their job, they want to do the above and then get out of Afghan as soon as possible. I speak to the parents who treat young children mutilated not by British soldiers but by the taliban/by suicide bombers/by people they know/by other Aghani nationals. and they're appalled but if we're not out there nobody will do a thing.
And to raise a point - you only hear about the death of soldiers not those harmed/injured/sent home due to horrific injuries. My friends husband was sent home with terrible injuries he is/was a para - he'd wanted to do it all his life - not to fight just because it sounded a great/interesting job - he probably won't get to be on the front line again but he doesn't blame anyone and is keen to get back to work!
