Enlistment Program 9B, ACASP, Option 19. Clarification?

Can a career counselor please elaborate on AR 601-210 please. In reference to the Enlistment Program 9B, ACASP, Option 19 ( Army Choice of station). I have read through the reg in this section. To my understanding a person enlisting in the ACASP program would fall under this enlistment program and be able to have option 19, just as they would option 40 or others. When signing contract, I would assume it would be "enlistee request a duty station, career counselor checks availability and projection of graduation date and MOS qualified status, and sets ship out date to that". Any clarification would be greatly appreciated. Long story short, my wife is enlisting in the ACASP program as a 68W with her EMT-B certification, and we live next to 3 army bases.
