army wearing marine combat patch?

I think the Marines will take exception to your wearing anything that says Marine.

You may be attached to the Marines as are Corpsmen, but they do not claim to be Marines.

The only Army Soldier authorized a 1st MEF patch are those who spent at least 6 months under the direct opperational control of the 1st MEF. This is outlined in AR 670-1. Like all awards It also requires the publishing of official orders authorizing the wear. Incidentally, Marines who saw combat with the 1st MEF and then join the Army (usually in the Guard or Reserves) are NOT authorized the combat patch. It must be earned while being a member of the Army attached to a Marine unit. MP US Army is wrong. I don't care if he is a CPT. I have orders published to wear the the 1 Cav and 3rd ID as my "former wartime service insignia" or combat patch.

The Army has tightened restrictions on the wear of Marine Corps logo patches as the shoulder sleeve insignia for wartime service, or “combat patch,” on soldier uniforms.

Soldiers who are authorized to continue wearing a Marine patch as their combat patch include those who served with Marine Corps units during operations that qualify for an Army combat patch, as prescribed in Army Regulation 670-1, and who have written approval from the Army chief of personnel or a delegated representative.

However, under a policy change that took effect June 11, soldiers in Army units at the company level and higher who are attached to, or under the operational control of, deployed Marine units no longer are eligible for the policy exemption that allows them to wear Marine logo patches as combat patches.

The change is designed to preserve the heritage of Army units, according to a directive from the Office of the G-1.

Soldiers who serve with a Marine headquarters staff as an individual augmentee are still eligible to wear Marine Corps logo patches.

The waiver policy for the wear of Marine patches dates to 2004, when the G-1 at the time, Lt. Gen. Franklin Hagenbeck, responded to a request from the Army chief of staff and approved their wear as an exception to longtime policy.

Since then, Army units routinely were serving under larger Marine Corps units, such as the 1st Marine Division, which has the Guadalcanal logo patch, and the 2nd Marine Division, which has the “Follow Me” patch.

Talk to your chain of command, it is not like you can wear it if you all do not get permission first. We wore a Marine Patch with our ACU's but we were not allowed to wear it on dress uniforms.

I would look at the army website and see if there is a point of contact you can email to get a affirmative answer. And this way you would have a record of that answer with a name.
