I've said as much for a long time. That "manly viking beard" shit doesn't look good at all, it makes you look like a homeless junkie. If you can't even maintain basic fucking grooming standards, you don't deserve to be in the military. Or in the workforce. Or even in fucking society at large. Go fuck off to the wilderness if you want to look like a bum with a yee yee ass haircut and druggie beard and faggot shit tattoos.
If you're a member of any nation's military, especially its variant of "elite forces", then you should look fucking immaculate no matter what. You should be the example every other soldier/sailor looks at for inspiration. Literally, you should look so fucking good that they could take you at any point, make you strike a pose, and put that shit on a recruiting poster. Not look like a fucking extra from a shitty PSA about why doing drugs is bad.
