They're both heroes, but I like the Navy better.
That depends if you like water or dry land more ! But marines do make amphibious assaults .
Those are fighting words...
You can't really compare them. In terms of who dies the most it's the marines. In terms of which one you'll get sexually assaulted the most, it's the navy.
They both get abused by unsrupulous politicians.
They each have a role and are "better" in their own right.
Better at what?
They both suck
