Why can't we grow beards?

I mean, there obviously had to be good reason to allow it...I just figured you'd find those interesting examples of instances where there had apparently been exceptions, due to some clear need and/or justification...I'd be most eager for your thoughts, you raise an interesting point, certainly, I just figured you'd find interesting seeing a couple of concrete examples of sites dealing with exactly that topic, honest, many thanks...

Read this, OK?

As I understand it, I've known of instances where, for cold weather, I've read of instances where it was allowed, either to retain body heat, or because shaving was simply impractical...I've also read of instances, I'm fairly sure, when Navy, I think, had allowed it...the problem is, as I perceive it, one of uniformity...if you give a human an inch, they're pretty much inclined to take a mile. Gas typically expands to fill an available volume...once you unlock that Pandora's Box, it's kind of hard to shut the door again, you know? There was something else I'd thought of that you might find interesting to read, let me try to find it first, OK?

Well I kinda agree. I mean i did contract on base and dam the amount of soldiers that dont know there mos is to include the dam higher ups that are definitely supposed to know is amazing. I mean I understand if your hidden away for months on in in a office and only see the vehicle your supposed to operate 1 time a year but for the others no excuse. 88ms and what ever the mechanics code is now. There are some dumbass soldiers now

Because someone with a vagina said it looks gross.

Grow your beard when you ets and become a contractor. Then you’ll have the best of both worlds

SSG(P) (Join to see) - Beards interfere with the proper wear of gas masks. In the same camp, the hair styles that are authorized for females also cannot interfere with a gas mask.

DON'T see what the harm is with facial hair or leangth of hair. Neither one hampers the ability to fire a weapon.

same reason why they wont let old people join or re join...Some men cant grow beards and would feel inferior or be bullied by those with the ability to grow a full beard while eating breakfast....lol. The age limit is there because old men in their 40's cant usually perform the rigors of basic training and while we can maintain our physical condition and perform at or above standard on the APFT the idea of some 25year old staff sergeant yelling in my ear is would be alittle hard to swallow, tho i would love the opportunity to try it once more this time with the more mature outlook than I had at 17....actually I think 40somethings would make fine recruits to support MOS's or even team oriented combat roles...infantry may be a reach for some but that could be determined on a case by case. Beards would be cool in the navy, in the special circumstances in special operation areas but at the end of the day just like aged men in basic traing doesnt look good a clean shaved soldier just looks better than a bunch of scraggley beards...just my opinion.
