The branches have always had a rivalry between them, it is the natural order of things. Hell, within the branches there is rivalry between the jobs. All in good fun. I have the utmost respect for the Corps, and always have. To each their own place in the world.
The branches are so closely integrated in operations these days that I don't honestly think any one of them would do as well without the other.
Peace Sauce, and thank you for doing what many couldn't, or won't do.
