I was supporting the new Lieutenants entering The Basic School (TBS) for the Marine Corps.
There were a couple of females who showed up and were about 5' 1" or slightly taller and weighed less than 105 lbs (I know because I asked them).
Their Company trainers decided to have the troops stay out in the field for Range Week and they ended up packing 120 lbs packs to march the four miles to the ranges. The two females could not walk the four miles with packs weighing more than 15 pounds over their body weight. They both fell out of TBS.
How did they make it through officer candidate school in the first place?
