“Literally being at the tip of the spear, in the mix of things, is where I prefer to be.    We have no doubt, being here and doing the missions we do, that we are doing important work and can see firsthand why a strong Navy is so important to national security. I go to work every day knowing that what I do is important and our training is more poignant knowing we could actually have to use it out here.”

  1. There are not two types within the MR Rating and the schools are not 18 weeks long. That was taken from a very old reference.

    1. Hi, Chief Decane

      Thanks for pointing that out. I got the 18 weeks long “A” school reference from the Navy COOL Machinery Repairman (MR) Rating Card (which claims it is current as of 06/19) and the two jobs reference from the Navy COOL Summary For Machinery Repairman (MR). Both are listed in the References of the article.

      If you can point me to a more accurate source, I’ll get the article updated.

      It’s most appreciated.

      Thanks,

      Travis
