I see videos of the "3 Para" squadron in Afghanistan, for example, and I wish I could live an experiance like it
Be very very very careful what you wish for. Done several tours in Iraq, thought I had seen most of what was on offer. Spent last summer in Helmand, spent 2 months mostly sh1tting myself. I wouldn't change my experiences for the world, but just be careful - You Tube videos are one thing, doing it is very different.
