US Army Cavalry Scout?

I swore in 2 days ago and my MOS is 19D (Cavalry Scout). A few questions. 1) Is there a Cavalry Scout Base in California? And, if possible, can you tell me where all Cavalry Scout bases are in the US. 2) How often do they ship out? Give an assumption if possible. And 3) When I do get shipped out, will I get hazardous pay?
