Prior service 11C reclassing to a Bravo. Any tips?

They are going to teach you everything and your only a SPC, so I would not worry about it. I wasn't a pure 11B either but so much overlap between then 11H (TOW) and 11B it was practicly one in the same our movement was on jeeps but almost mimiced exactly the movement on foot at times. We also parked the jeeps and did purely 11B stuff on foot as well. There really is not that much additional stuff to master beyond what you know as a 11C already. Just tactical movement which you should know as a 11C, Patrolling, and assaulting / clearing buildings and bunkers.

I think it's the same for both MOS's, I was FDC in an infantry unit and I was 11B, we still humped around, but with the 81's, that tube and base plate was heavy. At Bragg, I used to jump out with three 81mm rounds tied to me.

You’ll be good. Just do what your leadership says, and take every training opportunity you can get.

It sounds cliche, but train how you fight and muscle memory are both very real and effective things.

Back in the day, I had 2 MOS’s. 11C primary, 11B secondary. The only difference at Fort Polk AIT was we had 3 weeks of mortar training. My 1st 4 months in Nam were 11B. So there really is no difference.

I did that same thing many years ago.
FM 7-8 or whatever it is now.
Ranger Handbook
It is constantly moving not waiting for a fire mission.

You’ll be fine, just read some of the ranger handbook and get familiar with patrolling.

In truth, you are not 'reclassing' and changing your designation. You not moving from one field to another but simply dropping some additional skills and picking up a couple more. I will all come back and just remember to roll with it and you will be fine. The change from C to B should be able to me made with a 4187.

Know your battle drills and skill level one task TCCC and be in shape and you should be fine

Good evening SPC (Join to see). Excellent post. Thanks for sharing this Specialist. You bring up a good question. I recall when I was an 11Bravo and stationed at Ft. Knox in 2010 we had a few Chucks in our unit. They pretty much did the same training.
