It is an easy scenario, just pick. Quit dodging...
Ok I will pick an option from your un-realistic scenario.
I pick the female Marine platoon over the army platoon.
Why? Because the Marine platoon will have infinitely better leadership, better marksman, and will be better motivated.
And I trust any Marine more than I do a soldier.
Now that your crazy azz scenario is out of the way maybe you would like to address what I stated in my original post.
