My dad got me to join Special Forces, so I did. Then got a serious knee injury while exercising 3 days before me and my class were to wear the green beret and got transfered to Lemnos. That there was the beginning of my summer vacation.
From June to August and only for weekends, we could request transit via vehicle to a closeby beach. The heat was the only hard part. Other than that, during the day, I did as instructed. The evenings where uneventful as they should be. And after a while the newbies joined, so me and my class became "invisible". Got discharged on September 23rd of '16 (or October, not sure).
Tbh, your service is probably gonna be relatively better, considering you'll be home for a week both on Christmas AND Easter. Add to that the days that you can request to leave, soo... I'd say that the moment you return, right after Christmas, to the military facility that you will be stationed, you'll notice that your service has unofficially ended.
Unless some REAL SHIT happens. Which is very unlikely. Most of the "border invasion" thingys that are reported in the news are a legal way to justify some military expenses. Everyone knows it so they just play the part. If anything slightly unexpected happens, it will be resolved in a week or so. I speak from experience.
Also, you might get to experience 1 of those special exercises (or however they are called) that happen, where almost everyTHING and everyONE is mobilized in a mock-battle. Quite a thing to witness and experience. I don't want to get into many details, even though all those info are mostly open to the public and sometimes uploaded to the internet.
