On my first airliner landing, on the initial descent, I turned to my Line Check Captain and informed him that I hadn't flared a landing in 12 years. I didn't flare one that day, either. One passenger eyed me as he exited and said, "Naval aviator?" I threw an apologetic smile and he nodded gravely. Deplaning the next flight, an elderly lady asked (in the nicest possible way), "Are you flying me back home?" I told her that she was safe unless she was leaving in 45 minutes. She replied (in the nicest possible way), "Good."
It turned out that I was misapplying another, similar aircraft's landing technique and started greasing them on the next day as soon as we worked out what I was doing, but it was a rough couple legs. Since that time, I've prided myself on being able to land the aircraft with a decent amount of gentility. I still hate to float a landing, though, and will take a solid one rather than land half way down the field. It might be all those carrier traps wrapped around my DNA.
With regard to landing military aircraft, it is absolutely true that most carrier aviators land differently than land-based pilots. Even at the field, we slam it in every time (with some exceptions). One loathsome pilot once remarked, "Squat to pee, flare to land." I don't even know what that means, but we spit upon him and averted our gaze as he slunk off.
Edited for the expanation: The flare is when the descent rate is slowed so as to lessen the impact velocity with the runway; this includes reducing power so as to still allow the airplane to descend as the pilot is pulling back on the stick. Greasing a landing is making it particularly smooth. Floating a landing is when the aircraft has too much speed in the flare and literally floats farther down the runway than it should.
