Do you think that the various branches should have the same uniforms?

Ahhh Heck no!

No. Each branch has their specialty. I wouldn't want to ask a sailor if they had their tank ready for a ground assault.

We should all be wearing the same uniform. We are 1 US military. The navy & coast guard different for ship based uniforms.

Cammies/utilities can be the same, we were fine sharing in the 80s and 90s. Sleeve rolls and covers/hats varied by service and worked fine with differentiation. Service/Dress uniforms should be different.

Different uniforms define who we are and what we do. I believe that the PT test is still different from one service to the other and when they make all requirements the same then they should share a uniform.

same uniform for all branches seems a "silly" idea from both a tactical standpoint and a pride in service standpoint. The Army and Marines (plus a few special warfare units) all need cammo. The air force has no need to "hide" from anyone in nearly all cases. the Navy (except spec ops people) WANT to be seen. the present blue cammo the navy has would make it grossly hard to find someone if they fell into the sea. Coast Guard has less reason than the Navy or Airforce to need to hide.

The different services have different missions, the uniforms should reflect on and complement that mission, work, field ,or dress.

The Marine Dress Uniform is (in this man's opinion) the best looking one of all the services. I think all of the services should have the same style dress uniform as the Marines, except the color, awards, patches and insignia should be different so the different services are easily recognized.

Canada has a single uniform and it can be confusing.

The Military branches have an identity , each all their own. That identity molds the Soldier into that ideal Soldier for that specific purpose. We all wear Old Glory and that’s the only thing we need to be a cohesive fighting unit, leave us our identities.
