Are Army O-3 collar insignia they exact same size as Navy O-3 insignia?

Are you switching services and trying to save money?

The difference is where the cross bars meet the vertical bars. Dept of the Navy O3 tank has the cross bars at the ends of the “railroad tracks”. Army and Airforce have the cross bars offset inward about 2 mm.

Backstory: Going In for pha/pfa with a different reserve unit. Was told to where khakis. I can’t find my Lt. Insignia since generally wore the blueberries. The base exchange has Army Cpt. Insignia and a few people said to just do that but frankly I just don’t like being out of uniform so I wanted to confirm. I called around and found a helpful LT. who is letting me use his for the weekend. Thanks everyone for helping me get the little things right.
