Positioning the Ribbons and Badges on Service and Blue Dress Uniforms

Start by aligning the thickest badge, the rifle shooting badge, ⅛ inch up from the pocket. 

When two badges are worn, they are symmetrically placed on a line with about 3/4 inch space between holding bars. 1/4 inch spacing if three badges.

Align the skinnier pistol badge with the top of the rifle's holding bar. 

This may cause the pistol badge holding bar to be greater than ⅛ inch from the pocket. 

Align the ribbon rack ⅛ inch above both badges. 

Center the breast insignia 1/8 inch over the top ribbon

Most Common Uniform Questions

How do I place my USMC rank insignia on my collar?

On the utility uniform (MARPAT or cammies) the enlisted grade insignia is placed on each collar with the single point up and the center of the insignia on a line bisecting the angle of the point of the collar.  The lower outside edge will be spaced equally with 1/2 inch from both sides of the collar.  See the Utility Uniform page for pictures and more details.

On the Service Uniforms, place the insignia 1 inch and parallel to the collar.  

What are "Chucks"?

Service Charlies

"Chucks" are the Service "C" uniform.  They include a short-sleeved khaki shirt and green pants. Ribbons, badges, and breast insignia may be worn at the individual's or commander's discretion.  See our Service "C" uniform page for more details and pictures.  

What is the difference between Blue Dress A and Blue Dress B

Blue Dress A is with the medals.  Blue Dress B is with ribbons and Badges.  Blue Dress A may NOT be worn out in town. 

What uniforms may I wear off base, out in town?

All uniforms may be worn off base for leave and liberty EXCEPT Blue Dress A and Utilities. 

When driving to work, you may be in cammies, just do not get out of the car unless in an emergency or accident.  Per the order, getting gas at the gas station is not an emergency. You may go through the drive-through in cammies, just do not get out of the car.

You may wear Blue Dress A off base at command-approved functions, such as the Marine Corps Ball. 

Can I wear my Marine uniform after I EAS?

Yes, if you received an honorable discharge, but only on certain occasions:

"former members who served honorably during a declared or undeclared war and whose most recent service was terminated under honorable conditions may wear the uniform in the highest grade held during such war service only upon the following occasions and in the course of travel incident thereto:

(1) Military funerals, memorial services, weddings, and inaugurals.
