What confuses you most about "sister services?"
I always see other services just wear anything during their PT formations. Example the Navy has a PT uniform but in one formation everyone had on something different even brown t shirts. I thought that was hilarious.
Now for the Lt/Capt part. Yes I would agree with you on that. But, the Navy Lts. LOVE it when you call them Capt. Especially when you are from a sister service. And yes I did ask a Navy LT about being addressed as Capt instead of LT by us Air Force members.
Another thing about the being a Capt in the Navy. On very small boats, you do not have to have the Rank of Capt. to be a Captain of the boat. To command say a Cruiser or an Aircraft Carrier, Even the Battleships when they were in service, you have to have the Rank of Capt. If a Flag officer is on board, they are in charge of a group of ships. That is the only confusing thing with being a Capt. You can be a Lt Commander and be a Captain of a smaller vessel.
I'm a Sailor and I understand completely where you are coming from, not only the ranks but titles. Capt is a Rank O-6 and a Title Senior Man in charge of a Vessel no matter his rank is Capt or Skipper. Looks like Top Sgt Hurley beat me to the punch line. Also we Use your Job Specialty as part of your rank. Yeah!
Now for you "OLD" Army guys. Explain the Army ranks. Especially the third and last rows. I have found more ranks that the US military has used over the years. And they are just as confusing.
Then its a simple breakdown that doesn't require counting all of them:
a stripe around the star for each junior enlisted ranks,
then stripes under for NCO ranks,
then chevron over for each rank of Senior NCO.
I'm still working on the names :-)
PV2 Wilcox, I think you are incorrect about the Marines hate Army folks, In fact I think the Army hate the Marines. Look at the Army Navy football games.
When Marines are aboard ship they become Ocean Going Bell Hops, Holding the doors for the Flag mess.
Or What else would you put marinara sauce on but Squid.
But the biggest one thing that the Marines have going for them is that they are the Men’s Dept. of the USN.
All else aside, we rib each other just like any kids from any families so, fight tooth and nail with each other but let ANYONE else start in with any of our brother or sister in arms, Katy-Bar-The-Doors, a barn clearin' is a-fixin to start.
Kind of like grade school, if we didn't love 'em we wouldn't pick on 'em
