If you're asking for experiences, I must say that you'll get as many different experiences as there are people replying. It's like a lottery; sometimes you win big time and sometimes you lose it all. Perhaps the most notable things that affect the service is a) where you're "doing your time", a2) what 'profession' you're 'learning', b) how well you adapt yourself to the situation and perhaps most importantly c) the people around you as you'll live with them quite closely for a couple of months...
I personally saw quite a few different faces of the army as I served in two completely different units during the six months they kept me there. And the most important thing that contributed the mental well being was the friends around; no matter how !"#¤% the task at hand felt - you weren't suffering from it alone. So sociality helps. A lot. Then again, after being transferred to the new units, my 'army' started to look more like the comedic moments of the show MASH.
Even though it's part of the big "conspiracy", the best way to get around is not to think too much about it, enjoy the experience (despite the frostbites) and not fight against the system over all small details as it tends to make your life a bit more harder. Then again, the sooner you learn how the system works the better, as you'll be able to use some of the holes to your advantage.
But yeah. A lot of it depends on your pesonality (and your sense of humor/ability to brush things off without thinking too much about 'em.) Just realize that it's a completely different world from the "civilization". I'd be lying if I said that I enjoyed it while I was there, but after getting out - I can't say I regret taking that road as it was quite an experience (if not all that positive every day.)
As for the 3 euros a day, sure it ain't much but it's not like you need that much money while serving. The army provides everything you need
(but some extra food during trips outside doesn't hurt the motivation.)
And as for the pictures posted, don't worry about it as it ain't that serious of a thing. "Perseily", in all of its various forms, is a good way to relieve the stress by laughter. Whether it's dressing up or just acting stupid. No harm done.
