In AH we can easily rearm and refuel our plane in 30 seconds. We change the configuration of the plane with few clicks in the hangar and fly again. We land a damaged plane and immediately get a new one.
Of course in the real life it takes more than 30 seconds to rearm and refuel the plane - but with a well trained ground crew a modern jets can be ready for takeoff withing an amazingly short time. You can't change the configuration with few clicks but in the real life can be very short (given the right crew). Good ground crews can return damaged or malfunctioning planes to the service amazingly fast. In the real world it frequently made a huge difference - how many sorties you can send to the air, how many planes you need.
Well trained ground crew can actually be force multiplier. An air force that can have fewer planes can partially compensate quantity limits with short turn around times and high sortie generation rate. There are many examples though the aviation history and IAF is one of them.
There are many books and movies about the aviation: many about the great pilots and great tactics, many about aircraft designers but very few talk about the man and woman (in IAF) on the ground that actually allow the pilots to "rearm in 30 seconds".
On a personal note: I served for 3 years in IAF as a mechanics of F-15 (it was more than 10 years ago), we worked hard every day and especially hard during around the clock training, I was like one of the guys on the photos below. I must admit, even myself, I was amazed what we were capable of doing in the real life situations.
