Why don't officers wear marksmanship badges?

Great topic. This can be viewed in many ways.

"expected to be experts" term....Gentlemen, you are experts. Now, Ruck up, spread out and move forward.

Non commissioned Officers set the example

Because Officers are supposed to be experts at everything. No sense in proving you can't hit the broad side of a barn.

Don't know why but in the Air Force after I was commissioned I wore my ribbon with one device signifying qualifying expert on two weapons. Never looked at other officers but in Security Police we definitely wanted all to know. Nothing we made any deal of but when you are going to the range as often as we did I didn't see a reason not to wear it.

I agree with the Colonel (Smallfield), for there are Officers whom are "Expert Snipers". Officers lead, while soldiers fight. In case of need, Officers will pick up a weapon and become a soldier but their primary function is to Lead men and women into the Fight. There is no need for Officers to showcase their ability to fire down-range, but it is essential that Officers know which soldier can do a far better job in firing down-range among the enlisted rank. Officers should NOT wear their ability to fire any weapon, such knowledge is a given that they can...

All military service awards and decorations should be proudly displayed for recognition of the professional achievements in their career. It shows great pride in their dedication and commitment to the defense of the United States Constitution.

Officers wear expert (if awarded) or nothing at all is the reason I was given as a new second lieutenant. Col T. Wright, USA Ret.

As a country boy I did okay in basic training and fired expert on the M14. A little later , after commissioning, I found the 45 caliber pistol to be a area denial weapon and could not hit squat with it. Then I bought a 45 caliber colt pistol in a pawn shop in Aberdeen, Maryland. Took it to a gunsmith and had things tightened up. Things picked up thereafter...and it is a superb handgun.
Badges - hmm... I think we wear too many of them. Stick to the basics ...that identify with your core function. If you are an infantryman - the CIB....if you are Ordnance - the EOD badge...and so on. Generals today wear more medals than the mostly highly decorated heroes of WWII, Korea and Vietnam ( won for valor) ...check out the photos and the bios of Audie Murphy and the current CSA.
Final bit of advice : Work hard at being tactically and technically proficient ...and enjoy the voyage.

Honestly, I have always thought that it was a strategy to maintain their Soldiers confidence and giving the appearance of being the highest standard, even if they are not. LTs are already looked at, in many situations, as "over-paid privates" and if this young LT is only a marksman out would only reinforce that notion that officers cannot do "real Soldier work" and that officer loses some respect from his element. In a like manner any leader who struggles to pass an apft loses all respect when they smoke a Soldier. By not wearing the badge, their ability to perform this basic Soldier task is rarely, if ever thrown into question.
