How do servicemen manage their family life?

[THE GREEN MAN]

اسلام عليكم
OK this might come off as a naive question, but how do they manage it?
Officers and especially soldiers.
How often are they granted leave?
What about their Spouse and children, how much do they get to live with them.
Insights or experiences are appreciated.

With a lot of difficulty and give and take.
