There are multiple aircraft flying from any location. The busier ones require crews to be launching or recovering for 12 hours a day, 120 days straight, and the less busy ones are similar but less compact scheduling.
No one deploys constantly; everyone flies MCE missions stateside. It's a compartmentalization like any other because the squadron environment is at the squadron and isn't like your home, and your home is at home and isn't like your squadron. You drive to work and then, like other professionals, brief the sortie, fly the sortie, debrief the sortie, and leave the sortie at work before driving home. Sometimes it involves having seen frustrating things, having seen graphic things, or having felt really good about some assistance you provided...the end state is all the same, though, it stays at work.
