Go on their site. somewhere there they will have constituent information. Under that tab will be nomination information. If the 3rd MOC is having all of the info, including application sent to their DC office they may be reviewing the packets from there.
Not every MOC will have a local committee, or do interviews to give a nom.
I respect Flieger and Luigi, but have to disagree with sending them via collegeboard using their number for a couple of reasons.
1. You can only send 5 without being hit up to pay for other internet copies. Apply to 3 SAs, and 3 MOCs, you are already paying for it, before you ask the scores to be sent by the board to ROTC scholarship hq's, and your traditional colleges. SAT costs @80, sending electronically can quickly bring you to a 150 bill, take the SAT twice, and ACT twice, now you are up to 600. That is a lot of money when you also start popping out 50-75 for each traditional application. In the end it could cost 1K just to apply for college. Not every candidate will only apply to an SA, many will have at least 5 back ups since they will be applying ROTC scholarship too. 1K to me is a lot of money to spend just to apply to college. Now remove the electronic copies, and only send them to the required parties and that bill can be cut down by a couple of hundred bucks. *I guess that is the cheap military wife in me trying to stretch a buck!
2. I would not suggest sending them through college board unless the MOC has requested that method, because it could easily get lost in the shuffle. Only one of our MOC's requested/demanded this method. The second gave the option of the college board or hard copy. We chose the hard copy so we knew it went complete. The third stated DO NOT send it via college board only full applications with hard copies would be accepted.
I would also suggest you contact the offices to find out if they will accept a copy of your SAT/ACT from you. Our 2 MOCs allowed this since they also required a sealed transcript that included the scores...no way to cheat since the transcript would verify the scores. If they allow this, I suggest this way to go because that will allow all of your packet to arrive together at the same time. There is no fear that the scores could get lost. It also goes back to saying money...this allows you to not use them as one of the 5 freebies allowed by the collegeboard.
In your case, I would suggest you contact the local office for them. Every MOC has an office within your state. Contact them there. I know for our 3 MOCs they had a dedicated staff that only worked on SA noms/apptmts. Ask for that extension. ***Remember introduce yourself clearly, and thank them by name. When you hang up, write down the time, the date and the name, place it in a file. Send the application via snail mail with a signature guarantee card. Contact them @ 2 weeks before they close the applications, ask for that person, restate your name, and politely state, you are just making sure they have everything complete in your file for the nom. selection board.
