What planet are you on Aitch?
I bet people killed in car crashes never think it's going to be them either, nor do their families. Aren't we all in denial every time we step into a car? We HOPE in the Forces that it's not going to be our family members killed, but we are all too aware that it might be. You cannot however live your life like that, so we get on with it when they are away. We all plan for the worst and hope for the best.
As for 'brainwashing probably isn't even the right word, re-programming and ultra-bonding maybe, stemming from shared training and living experiences, even for the wives and families? you do all have to buy into this noble hero thing.' Big fat hairy swingy bollocks is all I can say to that. As far as I know, I have not been brainwashed, had to go on ultra-bonding (ugh, it might involve physical activity) or re-programming sessions. My ds certainly hasn't. I married a man who does a specific job, which I am aware might kill him. I am also aware that that entailed the possibility of him killing others. For much of his career, the Cold War was the one being fought, and so the possibility of killing someone in his particular specialisation was remote, although his safety when away was a constant worry.
The Army Officer on Radio 4 probably was excited at being deployed because he could put his training into practise and exercise his professional skills. At the same time, he would have been apprehensive and scared and wanting to get on with the job in hand.
As for the Civvy street jobs - not at the level of pay and job security that can be commanded in the Forces. The job security is important, especially as the salary is guaranteed by HMG.
Truly - that 'not in my name' bleat always reminds me of Pontius Pilate washing his hands. If fighting in Afghanistan prevents the Taleban from getting stronger in Pakistan and gaining control of the nuclear weapons there, then good. That would really mean that the shit would hit the fan if that happened. If you are a tax payer then your comment about indirectly killing can be applied to you, as it's your taxes that fund the Armed Forces, buys the munitions, the food, the uniforms, the equipment. If you voted Labour, then this is in your name, as you gave Blair and then Brown the mandate to send and keep the troops there.
