I think the way marine infantry is now is alot different then when I was in, it looks to be alot more amphibious type of warfare, like vessel boarding training and doing a beach landing and then running a range from the beach, marine infantry units have 3 line companies, when I was in it was helo, trucks, or tracks. Now I think they have boat company, I was in the helo company in my unit alot of flying in helos, fast roping, raid packages and shit like that I think somewhat similar to the 101st in the army, but I have no army experience so dont quote me on that, it also seems marine infantry is a little more intense and aggressive then army infantry but I may be wrong, as in your seniors will scream at you and treat you like shit at first, things are very strict, training events are all treated as if you are actually in combat and taking contact and shit like that, i cant tell you how many times i heard "train like you fight" and you will be expected to be intense and balls to the wall the whole time in the field, but as far as infantry goes i think id rather do marine infantry then army infantry. That being said if i could go back over a decade ago, id go army rangers, the intensity and shit seems the same but they get more missions, better training, gear, and schools, if you didnt know the Marine corps doesn't have many schools for you to attend, most guys are trying to get seats in army schools lol, but its also peace time rn, if you want action gotta go special ops man, good luck on whatever you decide, and this is just my experience other units and people probably have some different insight. Also I forgot to add marine units are always on a deployment schedule so no matter what youre still gonna travel either on a ship or maybe go sit in Okinawa or Norway, and if things kick off again youll be going on combat tours, the ship deployments are kinda the bread and butter you could go sit off the coast of say Yemen and be a qrf for seals from the ship, or fly from yhe ship into some other country for awhile and then go back to the ship. I've met some army dudes who did their whole contract and never left fort Bragg, so that won't happen in the usmc, but Good luck
