- If I patrol the area for 20 hours , save the game and continue the game the other day , this time I patrolled is also saved ?
Unfortunately , it is not...You shouldn't reload the game or leaving the area until those 48/72 hours are passed. However, if your patrol timer is reset from some reason, it is not the end of the world (You'll stay short for just a couple of promotion points). This also means that you certainly don't wont to miss approaching large convoy just because it is outside of your patrol area...
From what i can tell you, you cannot. You just have to stay there for all the 48 hours without leaving the area or quitting the game session.
BTW, i got that from
