If you have a good unit then most of the military experience is hanging out with your friends all the time.
Except for the 5am PT every morning, and at 7am when you've got to get your truck ready at the motor pool, or 8am when you've got special duty to set up the range, or 9am when there's a 2 hour briefing about keeping your hands to yourself and having a designated driver.
Lunch at 11am is usually alright, except the base you're at has the worst DFAC you've ever seen.
That range you helped set up? It's at 12am, and it's fun to blast away at targets thinking about how much weapon cleaning you're going to do tonight.
There's a lot of leftover ammo, but you only had to shoot 2 magazines, so your rifle isn't going to be that hard to clean. (Any vets know what's coming next?)
First Sergeant says we can't waste ammo, if we don't use the 10,000 rounds they give us, they will only give us 5 rounds next time.
So the next several hours is spent in the sun, loading more rounds to mindless blast in the general direction of targets on the range.
7pm rolls around, it's quitting time. Just kidding, night land nav, time to stumble around around in the dark with shitty NVGs and try to find all the points scattered throughout 2 miles, using nothing but a compass and a map.
Except nobody ever gets all the points, so everyone gets together at the end to share the points they found.
10pm, now it's quitting time, except wait, some moron has lost their night vision goggles, so instead of going back to the barracks, everyone is going to spend the night on the land nav course until it's found. In the morning it's found right next to one of the vehicle tires.
Those are the general events of a somewhat easy day in a combat unit. A day without overnight watch, hours of formations and drill ceremony, 30km ruck marches, endless briefings, flipping landscaping rocks because first sergeant doesn't like the side you flipped everything to last month, etc etc etc.
For all the problems the game has, the major thing they get right is the environment.
Almost every area looks more than great, some are industrial, luxurious, barren, creepy, outright hostile, or cozy, but they are usually always gorgeous.
The environments are what pushed me to keep giving the game a chance after the initial shock of not having a cohesive overworld.
