You don't have enough posts, someone will do it - I'm not sure if it needs to happen but I don't like discussing any more than what needs to be discussed and there's no need to disseminate information like that even if it is on google.
Another note:
I hate how the career decisions you are making are in the aspect of "I want to be in combat."
From a large perspective, any of the jobs listed in this thread grant you that ability but you are knit-picking to achieve maximum efficiency in something that only lasts less than an hour (most times). You're putting all of your eggs in the wrong basket. Lets also assume that you don't get killed in the process of any of these COAs (or medically discharged from training injuries).
Most of the students graduating ITC are Corporals & brand new Sergeants. Soon they will ALL be Sergeants and they will all be competing with each other for Staff along with the next class, and the next and so on. Some of these guys will end up bag holders, meaning, they will not be reenlisted.
The Marine Corps is not a perfect functioning system, it functions to mission completion. They do not give a fuck about dropping a guy like you who will likely only get one deployment (if you do) in before you are up for selection to Staff. Seriously, fuck around and get passed over - not to mention the fact that you can never leave the unit to do anything else. You will start swirling in a community you know nothing about and eventually, before you know it, you'll be stuck in the frat house with all the dudes you either saw in A&S, ITC, or some guy who was an asshole to you as your EL or Ops Chief.
Bro, you are about to commit your entire career to an organization you know nothing about and you're doing it to achieve combat bona fides and please do not pretend you are doing anything else in this situation. There is a major tractor trailer full of bullshit that you have to go through in order to even find that, some dudes never even deploy to legit combat AOs but you want to do all of this for that?
If you go with Counter Intel or EOD - at a perfect entry, you will not only have a greater chance of success (in achieving this Valhalla Whiskey Bourbon Trail you seek) you will also find some serious promotion opportunities, self-sufficiency, a smaller community to tap into, and a huge network of spaces to insert yourself after the Marine Corps.
If you go to MARSOC as a CI guy or EOD - yes you will see combat; afterward, you will move on with your life and continue to do good shit, as a guy who can leave and come back freely with literally a position that nobody can really replace or question.
