I'm rooting for the UFL, so I was sorry to see this. It's an embarrassment for the league.. really bad optics.
But in fairness, I don't think the UFL did a poor job promoting the military.. it's more that young Americans are increasingly realizing current American foreign policy is uninspiring. There's almost no self-interests for the average American in today's foreign/military policy.
There's still the draw of military benefits (health care & school subsidies etc), but.. I think as long as American foreign policy is incoherent and the American empire is in decline.. military enlistments will stay flat or shrivel.. no matter how they choose to advertise it.
Military is losing it from former military because of the GWOT (global war on terror) and "people talking". You can learn the "real life" from those who lived it without the "window dressing" you assume is related to military life as a civilian. The humor channels provide satire that makes you laugh, but the scenarios, if taken seriously, are such that would wake and deter a delusional recruit in previous generations. I mean, just watching all of Yusha Thomas's youtube vids, and you'll get a sense of what Army is like. And even Thomas himself might have some skeletons in his closet.
Lujan and WhistlinDiesel(featuring her) has done more to fish recruits than football.
Enlistment is essentially signing up to be a janitor with flair and then a disposable grunt if things get "hot".
Also, the military has some checks to make sure it can't threaten the top. The two-tier system of officers and enlisted plus the hostile environment basically is designed so most don't stick around too long.
Also, reading that...lots of army BS in there. Even the "loss" of 38 enlistments sounds like painting victimhood and the internal dispute on whether to sign the deal. Welcome to the dog-eat-dog nature of the Army.
