Why don't officers wear marksmanship badges?

I used to shoot Expert, and I had the jewelry to prove it. But the most memorable "qualification" I received was in April, 2006 in Afghanistan. After watching our ANA shoot, for the most part poorly, we took a little time to verify our zeros at 100 meters. One of our SF NCOs looked at my target, then turned to me and said "Yep, you're a killer." They don't make a badge for that.

Some Officers do wear Marksmanship Badges. I just depends on the type of Badge. I have know a number of Officers that have warn a Distinguished Rifle or Pistol Badge including International Distinguished Rifle or Pistol Badges.

One component of this is the collective leadership of the battle that officers are trained and equipped to lead, and all USMC dogma aside, all Army officers must qualify with the basic infantry rifle to earn the commission. Their recognition and awards - and efficiency evaluations - are about what they are able to achieve with their unit.

When I was a Lieutenant in the 82nd Airborne Division, I learned that the officers of the 75th Ranger Regiment were required to wear the marksmanship badges they had earned, and those badges had better be Expert badges. It made sense that all leaders in the 75th were expected to set the example, so a lot of us in the 82nd decided to do the same. I wore my Expert badge on my Class A’s until I retired, and I kept it current too.

Never wore marksmanship badges as a warrant officer, just didn't. Don't have them in a retirement shadow box either.

When I was a new Lieutenant, I was told that officers don’t wear marksmanship badges because it was assumed officers always qualified as expert. Yes, I know, ridiculous. The other maxim was that as an officer you were required to max you APFT every time (which I did until I tore my ACL). It was the whole, “zero defects” mentality which the Generals swore didn’t exist but really did. One mistake, you’ve seen your last promotion. Hopefully things are better now than they were when I was on AD (86-2008).

Officers are expected to be experts in everything. Wearing or not wearing a badge does not change that expectation. Wearing a badge says yes I am an expert, here is my badge to prove it. Not wearing a badge allows it to remain implied that that I am an expert. The dirty secret is: NO ONE CAN BE AN EXPERT IN EVERYTHING. Being an officer, subtlety is one of our secret weapons. Knowing who is an expert and delegating or deferring to a subject matter expert is one of the best skills an officer can develop.
I am not a Master Gunner. I don't know the ballistic coefficient of every weapon in my MTOE. I know the Master Gunner. He can rattle that off from memory. I can cook an MRE and spice it up to my liking. But others would not like the food if I prepared it for a company or battalion sized element. I am not the first cook. I let cooks handle cooking for everyone... (and I should let the troops eat first. They are the ones doing the work.)
Stick to this:
If you can't figure it out yourself, ask a NCO you trust. Make sure you verify before you execute. You can trust me and what I say because I am a Retired Officer. Also, did I mention that I am an Expert at everything?

This is a very good question. Some years ago (1986) while attached to 1st SFG(A) at Ft. Lewis, I had a platoon sergeant (who was an SFC(P) and very conversant with AR670-1) who was acutely aware of the fact officers did not wear marksmanship badges. He then removed badge. He was occasionally challenged by inspecting officers in formation but after explaining that officers are not exempt, per regulation, from the wearing of the badge in question but do not do so, they left him alone.

I always considered it a thing of officer pride, rank seniority, and requirement of respect. No group of officers would ever want anything to visually show that they are lacking any superiority of skill that the soldiers they lead are required to have. I’m not saying it would ever happen just over skills in weaponry, but their are some lower enlisted knowing no idea of things yet, who might feel their officer is lacking when the only thing they display is basic pistol marksmanship while they’re currently an expert and sharpshooter in a number of different weapons.

I was always told that it is something like you don't want to have the guy I'm charge showing that he is just a marksman when so many others are experts
