What is the typical pilot to aircraft ratio in military squadrons? On aviation.SE, we already find this question addressing the pilot to aircraft ratio in airlines. It states that typical big airlines have roughly between 15 and 20 pilots per aircraft.

Military aircraft may require less pilots per aircraft:


airliners are in flight almost all day long every day
a typical airliner flight requires between 2 and 3 pilots (the 3rd one for very long steps or as an instructer)
a typical fighter is a one-seater
a fighter flight less time than an airliner
military cargo may flight more than fighters, but I hardly see a cargo used as much as a passenger aircraft (I may be mistaken)
HALE UAV may require several crew per flights but I don't know how long are those flight neither how many UAV can be operated simultaneously by one crew


When searching the number of each type of pilots (fighters, cargo/airliners, UAV) per air force (whatever the country), it is easy to come across recruiting websites (with requirement to become a military pilot and salary) but I fail to find anything about the number of pilot an air force has.

My question is : What is a typical ratio of pilots to aircraft in a typical military squadron? Does it differ between fighter squadron, transport squadron and UAV squadron?
As has been said, there is no one exact rule, but a broad estimate can be easily produced.

There are 12,500 active duty pilots in the USAF, and the service counts just over 5,000 manned aircraft. This will give an overall, rough, ballpark figure of 2.5 pilots per aircraft across the entire force.

Counting aircraft types by pilot seats, one can calculate the total number of pilot seats at around 8,350. About a thousand comes from training aircraft, however.

This gives an overall approximate figure of 1.5 pilots per seat, across the entire USAF.

This is not distributed equally. As mentioned in the comments above, combat units tend to run relatively low ratios. With the recent shortage of pilots, especially ones rated for combat aircraft, it has sometimes fallen below 1:1 in some units. For transport and utility aircraft, there are more crews.
