Why is it that officers are considered unprofessional who wear mustaches?

I thought it was expected of Warrants. Isn't it a requirement for your packet that you have a mustache?

if its in AR 670-1; does it really matter? I am not concerned if someone doesn't "think" it looks professional. If I am in reg, go find some grass that needs to be cut

Don't forget those unpainted rocks or the bumpers that aren't aligned perfectly in the motor pool, Chief!

CPT Zachary Brooks , sir I would hope that not the case, however there was an old school mental process that placed it on warrants, much like they all smoked Marlboro, drank Jack Daniels and gallons of coffee. My mentors did not wear the "stache" and I was told quite promptly when I returned from the deployment by the ones who know best, HH06 and the kids, that the stache just isn't gonna go far in my house.

SFC Clark Adams , painted rocks that were already painted way to many times and I like the alignment of aircraft much more than bumpers at the motor pool!

Thanks for the clarification, sir.

Clean shaven for 30 years of active duty service. grew a full beard in retirement, wife loves it, keeps me warm skiing and kayaking. I will not, however, wear a uniform unless I get hair (all of it) into standards. The upside is I now go to Halloween as "the worlds most interesting man"

Well i like to be clean shaven MOST of the time but as a cadet in ROTC, i am the only one with a stache right now so I stick out in formation. You just have to practice good judgment with staches. I really only grow the stache in November(Movember) and use it as a unit competition for who can grow a "well regulated and distinguished stache". Judgement is key ultimately.

Reminds me of day one of Air Assault when I took a gig for moustache out of regulation, it wasn't. The Black Hat 1Sgt informed me that by the next morning, it had to be like his. He was clean shaven.
I shaved that night. Finally shaved it permanently when it developed a solid gray section right below one nostril that at a distance didn't look like gray hair.

It is a little known fact that many uniform and appearance standards are taken out of pop culture from the original time they were created. And everytime we get new commanders or chiefs of staff and it comes time to review and update those regulations, instead of going into them and seeing what is still relevant they just go with "if it isn't broke don't fix it". Gas masks in WWI did have a part to play in the banning of beards and mustache regulation but certain units that are not only allowed but encouraged to wear facial hair have different pro masks (got this information from a chemical bubba i knew several years ago). the main retort to why we have to be clean shaven is the seal on a pro mask, hair grows even when wearing a promask and is also alot stiffer in the first few days of growing, therefore basic physics tells us that we are more likely to break the seal on our masks in the first 48-72 hours after shaving then if we were allowed to have facial hair, of a well groomed and neat appearance, and it would be made to lay flat by the mask. The biggest problem I can see with updating the reg to allow facial hair is the wording of it and enforcing of it. you could spend years in one unit and their idea of a "neat appearance" may not match up with your next units or even the next 1SG or Commander coming in. now with mustaches, the whole argument about the seal could be thrown out the window if you look at where the seal is actually applied, the outside of your face. even a tom selleck stache would not interfere with the primary seal on a pro mask.
