Mids have plenty of chances to swim, but 1200 Plebes don’t fit in 1 pool. USNA has been at this a long long time. Most afternoons are a lot of classroom time, uniforms, etc. The schedule is like this on purpose. I mean they have air conditioning now! I know the current Plebes don’t think it works well enough, but it’s better than nothing. But seriously Plebe Summer occurs the same time year after year. PEP is at 6 am. During the day they have to rotate 30 platoons through swimming, sailing, o course, e course, uniform issue, and dozens and dozens of other things. USNA has made a large investment in these young men and women and don’t want to harm them. Also it’s a lesson in leadership in taking care of your people. One day they could be leading a platoon of Marines in full body armor in Iraq or Afghanistan where it’s even hotter. War doesn’t stop for heat and humidity. So how do you ensure your Marines can sustain the fight in this type of environment? Water, more water, eating right, Gatorade, watching your Marines for heat issues, acclimation (maybe not a day patrol on day 1 in country is a wise move). They are learning all this while also going through it. This is part of the leadership laboratory they are learning about. As the schedule changes, detailers have to adapt on the fly to ensure training continues without missing a beat. They then have to rebalance the schedule to ensure if that was a critical evolution how does it now fit in the schedule. The detailers and Plebes are all learning every single minute of the day. The lessons are applicable now and in the fleet.
