Accurately shooting a rifle is a specialized skill and only very few soldiers train to do this. Few soldiers get killed by rifle fire. Artillery, drones, air strikes kill far more. The ability to carry heavy stuff over long distances is a key ability for many soldiers.

There are numerous jobs in the military where physical strength and endurance is less important. For every soldier on the frontline, there are ten behind the lines. Administration, service, repairs, medical, entertainment, training, infrastructure, intelligence, communications, any type of job that’s mainly using machines.

Infantry and sappers are the role where this makes the biggest difference. If a tank driver, pilot, or mechanic is a woman, the difference is minor.
