Why don't officers wear marksmanship badges?

This has been covered before. There is nothing in Army Regulations that prohibit it. Marine Officers wear them, with pride, I might add.

I earned the marksmanship ribbon in enlisted Air Force Security Forces training. I was authorized and proud to wear it throughout my career and in retirement when wearing uniform at special functions. I also fired 9mm as a medical officer giving me a chance to earn the ribbon.

most likely because they have problems identifying the part of the weapon that they should hold on to

I never wore mine except for when I was a cadet. It was definitely culture that stopped me once I was commissioned. That, and that I was told by my commander that officers do not wear them.

However, my expert badges are proudly displayed in my shadow box now that I’m retired.

All the Marines I knew wore them, especially pistols.

FINALLY... after 30 years, I was sent my Expert Marksman (combat pistol) badge. You may scoff at me, but as a female captain in the Medical Corps it meant a lot to me. When I was active duty, females were not allowed in any combat positions and so I was denied the right to go to any combat-oriented school. To top it off I am (and was then) a physician. So the general attitude was "you're a girl, and a doctor. You don't need to go to these schools". The attitude should have been "no one takes the Medical Corps seriously in the military. You should go to these schools and set them straight."
They wouldn't even allow me to go to the Expert Field Medical school to get the EFMB.

This reminds me of the ceremonial uniforms of TOG. If you check our ceremonial uniforms, we don't wear our marksmanship badges, either. There are several parallels between TOG and the way officers do things. I'm always a fan of at least one uniform showing the bread and butter of our skills, though.

In the AF you never even get to fire a M16 let alone qualify. You shoot 50 rounds from a 38 and that is the extent of your marksmanship training. Even flying combat mission hand guns are optional

Could be, too many officers are not as technically proficient as they should be. I earned expert in rifle, pistol, tank weapons, machine gun, and hand grenade. I wore all the bars on my badge. That told the troops their commander knew what he was talking about when I said, “Let’s go train.” Lead from the front, especially in combat arms.

The reason i was given as i am a Mustang, is that as an officer, i am supposed to be expert in everything. It is also up to an officer, to uplift, mentor, and guide the enlisted to be, know , do great things. It does not do one well to out shine those that we are trying to guide or the reverse for that matter, to be shown that we are wanting. While i shoot expert in the weapon systems that i am authorized in, its not that important that i show it. If i am required that i am on the line, shooting the enemy, we are truly and absolutely FUBAR’d.
