Overwork as I described above was so bad that my son’s sub had a actual suicide watch for exhausted sailors. Morale was on the floor because of the 100+ hours per week.
Your remark seems to ignore the actual impact of the deployments which you try to minimize. For every soldier in the field there are 2-4 people in the supply chain and logistics. Then you have the psychological impact on the soldiers and their families. And it does not stop after discharge.
“Morale was on the floor because of the 100+ hours per week.”
In my day, in the surface Navy, 140 hours was not uncommon.
