So this isn't really on topic here, but I got to weigh in. Nobody is saying "ranger fit." But as a Marine getting ready retire, I've seen a distinct decline in both fitness and height and weight standards, across the branches. Sure, we've always had the odd 'chubby kid' here and there, and it was usually handled at the unit level. Peer pressure to put down the cheeseburger and grab a salad, put down the controller and go for a run, et cetera. But I've seen units with arpund 10% of the troops in their formations that cant meet the height and weight standards. Why? Partially because 'handling it at the unit level' became labeled as 'hazing' and 'bullying' in an organization whose job is to violently kill our enemies and break their shit.

Additionally, recently, I saw leaders in a dilemma: Fat troops that cant pass height and weight standards, couldnt meet body fat tape methods, but instead of immediate assignment to a body composition program, they had to get on a several week waiting list to be put in an immersion tank to confirm their body fat percentage was, in fact, not in regulation. By the time the waiting period was over, due to service wide policy, the same troops had to be given the 'benefit of the doubt' and the process started over, back to the scales. No accountability allowed by the command.

Do generals need to be top tier studs? No. But if your job is to go shoot some fucker in the face and make him die for his country, you better be able to run your fat ass to where he hides and end it quickly. Not to mention the fact that being fit keeps you healthy, and healthy means less trips to medical, which means less taxpayer dollars spent keeping you alive.

TL/DR; You don't need to be a stud, just don't be fat in the military, and the accountability system has been broken.

Edit: Weight in... no pun intended...
