If my unit deploys in mid-March, but I don't report until May, will I join them or be put on Rear Detachment?

There is more to this story. Why would an 11B Non Commissioned Officer ask such a question in the first place.

This would be my first deployment, been at JBLM going 4 years now with none and I'm 11B. I don't want to miss next available deployment, just want to do my job. Might sound like a novice answer but it's the truth.

SSG (Join to see) - I'd contact the gaining CSM and let him know. He could also set you up with the process (SRP, CIF, ect). It takes about a week to go thru the SPR and pre-deployment process. I'd get everything time-lined out so I could get out of there and with the unit as fast as possible. I'd PCS early if allowed. Obviously if you have a family then you have other responsibilities that you will need to set up expertly for them. Best of Luck on the deployment.

I would like to do the max 120 days early arrival. Hopefully my 4187 gets approved.
