Does anyone have any details on the Warrant Officer position of any 255 series? How’s the job, and what is the school like?

Good source. The job is great. You are the one man band when it comes to your unit. Schools are long and informative. You'd make some lifelong connections/friends there. We are a small Cohort (Warrants), so the more warrants you know and befriend the more support you'll have when/if you need it. School has a lot of Cisco with a firehose, Microsoft Courses, CompTIA, NetApp, later Project Management, etc. The big picture is making all the stuff work together and keeping it up and running.

I was Infantry as well before becoming a 255A.

255A, Server Stacks, Helpdesk functions, C2R Systems integration - and the odd duck job of SASMO OIC in a BSB or ESC. CCNA, MSCE, CASP, CISSP (All things I.T. with Knowledge on Networking, Switches, Routers)

If you are thinking 255S, think GIAC, CISSP, CEH, defensive cyber stuff

170 series - along the lines of 255S but more offensive cyber stuff

255N, Cisco CCNA, CCNP - Switches, Routers, STT oriented (All things Network)

Hope this tidbit helps. The best thing to do is find a Warrant Officer Strength Manager (WOSM). The packet process takes a little while.
