Experienced pilots cycled into training roles and later returned as leaders of newer personnel, keeping squadrons from becoming either wholly veteran or wholly inexperienced. Pulling skilled aircrew away from combat reduced the immediate quality of frontline units and was therefore a deliberate operational sacrifice. The benefit appeared later when those instructors returned as leaders of replacements they had helped train. Japan retained elite cohesion at the front, but its replacements increasingly lacked the training that withdrawn veterans could have passed on.

British and American instructor rotations lowered immediate frontline concentration but spread combat experience through replacement squadrons.
