How good does an MSM (Meritorious Service Medal) look for an E-4 with 3 years of service with no airborne, air assault etc.?

Air Assault is 11 pretty easy days if you have any physical and mental ability at all. The MSM is harder to get than AASLT. Even the NG has an air assault course.
You saved a person's life. That's kind of worth something to most people. Just don't be a slacker dirtbag who had one good moment!

All too often, awards are given for just plain being there. It is encouraging to see an E4 getting an MSM and obviously because of your rank, you earned that award. I stood in formation once while an officer got an MSM and one of my men tapped me on the shoulder and said, "he is getting an award for what you did" That comment was worth more than an award. It is knowing that what you did was over and above of what was expected of you. Keep up the good work and you will continue to excel both in character and rank.

Awards dont necessary show the kind of soldier the wearer is. You can be an excellent soldier with a bad supervisor that never submit an award for you or be brown nosing-good for nothing dude and have AAM’s , ARCOMS and MSM’s in your chest.... For me, your performance will speak. ARMY STRONG

I personally would be curious of the condition of how one could get that award with so little time in service

Asking this questions says a lot about what currently matters to you.

Awards do not means your successful, good at your job, a good manager or a leader. It means you happen to be doing the right thing when someone was watching.

Prove it wasn't a fluke by being humble and reliable when it matters most.

And for what ever the reason you received it, well done.

An E-4 with 3 years active coupled with an MSN to boot? I would drug test the entire chain of command that blessed off on this..

It won’t hurt but will provide a good deal of promotion points. I’ve known many good soldiers not get the award because they weren’t high enough in rank, in the opinion of the OIC and not the recommender. The only thing that will matter at FTCKY will be that you are lacking your AASLT Wings. NOTHING else matters in regards to what’s on your shirt.

Is this a humble brag? I would say earning an MSM as a Junior Enlisted Solider is excellent and it maybe the last one you earn until you make SSG/SFC. Very rare for a Junior Enlisted to be awarded the MSM as a PCS award. Have you already been awarded the MSM or has your supervisor put you in for one and you’re assuming it will be approved by the Divison Commander? Either way, congratulations are in order. A very rare thing indeed, Congratulations.
