The only "trick" I know is that you can take advantage of how the sentry order works to set up some automatic actions.. For example, a group of fighters on sentry, with orders: refuel, move here, sentry, and repeat. They'll stand guard until they run low on supplies, resupply, and fly back to their original location, and go back into guard mode until they run low again.

Nothing particularly impressive but I was proud nonetheless. ^.^
