I’d absolutely agree with Logisticus regarding the seriousness of the non-deployable Soldier issue – it’s a fight you’ll be expected to manage as a Platoon Leader and it is certainly something that Commanders at all levels are responsible to brief and understand.

More specifically to your question – there are Soldiers in the Army who are unfit and, despite your leadership, will remain so. They can lack motivation, or they can be physical injured. Either way, your efforts will not make drastic changes for these individuals. The good news is that there are Soldiers you can reach and resources available to reach them.

The Wellness Centers on post offer a lot of recourses, as Logisticus noted, and I’d keep a look out for their POC when you do your in-processing. You will also be able to leverage your Company’s Master Fitness Trainer, your PSG, and others across the immediate formation. Don’t be afraid to seek this advice. Once you are fully informed, my advice to you would be to come up with a legitimate plan, and follow it. Start with an assessment (can be the APFT, but don’t limit yourself here), identify strengths and weaknesses, and identify how much time you have in your training schedule to tackle realistic improvements before your next significant field problem. With that in mind, write down your plan, ensure you have buy within your formation and with your Commander/1SG, gather all the resources, and execute your plan. Do you best to stick to it, every day, not matter what happens. If it was important to you when you wrote it down the first time, it’s probably still important, even if other things are creeping in (don’t let the “tyranny of the immediate” overcome your actual priorities).

Whatever method you use is relatively inconsequential, unless you actually stick to the program. MilAthlete, PRT, RAW, and other programs are only as good as the discipline you and your Soldiers demonstrate in sticking to the plan and executing the reps. Again, I agree with Logisticus regarding being an honest broker here. Ensure that your plan is reasonable, achievable, and properly resourced. When you get buy in with the leaders within your formation, that dedication will reach the Soldiers that want to improve (and I honestly believe that the vast majority of them want to get better, no matter where they’re at). PT is as good as you and your formation wants it to be, so don’t let there be an excuse for it not being what you want it to be.
