Looking at the comparison with WWII.
Which is such a temptation for you.
In WWII only 10% of the soldiers saw combat. The remainder were support. Desertion didn't affect combat as much as desertion does now.
Currently that support is contracted to Halliburton and subsidiaries, and even the military affairs are given to "contractors", better described as mercenaries. Those quitting or deserting aren't counted.
However, they are paid so much it might be lower.
