You are completely missing my point.
My point is nothing about Action Surge, Second Wind, and Indomitable feel like Fighter features to me. These features could, and in ways used to be, Ranger class features and could make sense as Ranger class features.
I think they are class defining. Moreover, whether they feel like fighter features or not they are, they provide much of the difference between fighter and other martials and a custom class chassis that does not include those is not a fighter chassis.
Hell, Tasha gave Rangers their own version of Second Wind in Tireless.
Not really. They get tireless at a much higher level, with much more uses, it provides temp hps instead of hps and much less of them ... and requires an action to use instead of a bonus action.
Really only Extra Attack (2) and Extra Attack (3) feel like Fighter exclusive class features to me.
The question I was answering is what separates the Fighter from the Ranger. Those things all separate the two whether they feel like fighter features or not, they are. Also I noted you left out heavy armor, and that is a pretty big feature.
Yes but Fighters and Ranger share many fighting styles.
It's not that Rangers couldn't learn GWF. It's that they don't because it doesn't match their style.
RAW Rangers can not learn GWF without using a feat to get it. It is not on their list of fighting styles. It is not only GWF, Rangers also can't learn superb technique, unarmed combat, protection or interception either. The fighter has 11 fighting styles, the Ranger only has access to 6 of them, slightly over half.
It's not like fighters had access to advanced fighting styles or fighting masteryy to say "well rangers and paladins and especially barbarians don't train with weapon enough to get Great Weapon Mastery or Archery MAstery."
Barbarians have no fighting styles. Paladins do have GWF, but not Archery. Fighters have them both because they are masters at all this, not speacialized pockets like those other classes. As noted in the PHB
"as fighters, they all share an unparalleled mastery with weapons and armor"
Rangers having knowldege of giants, speaking Draconic, finding 4 meals in the desert, having a climb speed, and shrugging off exhaustion all feel very rangery... to me anyway.
Sure and they give up the things that fighters have but don't "feel" Fighter-like to you to get it.
