Swiss military is probably the easiest one in the world, a friend told me a story where they was making survival training in the mountains, they just sent the driver at the evening to McDonalds and he came back with a shit load of hamburgers.
Awesome! Yeah, mine was about playing volleyball with camp members, when I kicked the ball in joy. Over a thick treeline/high hedge. Couldn't get through it from below, so I walked around it and it happened to be a military base/staging area. I just went in and looked for a person to ask if I could look for my ball. He drove me to the barracks in one of those VW Transporters and told me to ask 'those soldiers'. They were standing alongside a long table, some 10m long, cleaning and/or assembling their weapons. Freaking machine guns and assault rifles. I asked if I could check for my ball on the field/treeline, and some even helped. Sadly we couldn't find it and my mom had to pay some 70 francs after she picked me up when camp finished. Awesome experience though.
