The TMS Instruction says docs "become" a mobilization asset after completion of initial minimum inactive duty requirements, which implies they weren't before that time, and the Manual seems stronger, saying, WRT TMS, that "members become a mobilization asset in the final year of this three year commitment," and WRT CSS docs, that "Such members upon accession by definition are advanced practitioners ready for mobilization after initial Reserve training (usually, 84 drills or 21 months)." Still, that's parsing, and there is "generally" and "usually" hedging in the language, so I take your point.
Nevertheless, if there is no such policy requiring docs to settle in with their unit or receive any military training prior to deployment, there is the unsettling thought that someone could swear in, be mobilized before he did any drilling or active training (or even, I suppose, before he did basic officer training), and then be deployed with only the deployment-specific training, which I imagine is pretty hectic. I can see why the Navy would want reserves to have some military training before they head out.
