It is based on the volume 4 page 289(jap). Here Uncle John( his pseudonym) ,who represent the UK, was talking about some weapon deals with the US' arsenal businessmen. After the US rejected the UK's requirement of " the new trackor with 41.9 tons and 500 horsepower ", they started talking about " the precision pocket watch(精密懷中時計) " that was even more expensive than main tanks(主力戦車) and main aircraft(主力航空機) in this era.

I think it just explains why the Reich will conscript whoever had high aptitude for magic and sufficient mana, regardless their human race, gender, or even age. By the way, in manga chapter 25, it also mentioned that even the Reich only has about 100 men of the highest rank (might refers to A or S lol) mages, which is equal to 3 wings.
