Which military do you refer to? A few individual troops may use air rifles to practice basic targeting skills, but I can name no US force that has airguns as an official training regimen.
Hanging out with the USMC shooting team, they were absolute tyrants on dry-fire. They were also absolutely correct. When I started spending my down time running dry-fire on the range, the 9 ring was the worst I saw on any slow-fire stage.
Watch the front sight all the way to hammer drop, even more crucial with a pistol. When your trigger control or grip is weak, you will see the sight pull in one direction as the sear breaks. If you didn't see it move, you blinked.
