I will start talking right to the points:
-Men loses from encirclement: all died, no prisoners ==> prisoners and forced labor mechanic.
-Men loses from "overrun": all died, with no escape or need a "retreat and regroup" mechanic.
-Men loses from ships sunk in docking ships: all died too.
...
Manpower with some countries is precious, but men are too easily "died" by some reasons that are unreasonable.
