I am a SSG that has been in the Army for 4 years, I am reclassing to 25B. I already have a school date. Is it a better career move if I decided to stay enlisted? Later down the line I plan to go Warrant for 251A anyway? I would appreciate any advice and insight....

SSG 25U,

IF you decided to stay enlisted i would say that you made a good choice. 25B have many available throughout the Army, more choices than 25Us. B's can be stationed almost everywhere, it does not need to be a signal unit. B's promote from E-1 thru E-9 only competiting with only other B's. U's compete with most other Signal MOS's at E-9.
Since you are wanting to become a 251A, which corresponses directly with 25B work, you choose a good path.....In my opinion
