My limited understanding of

someone joining the Reserves who ultimately gets deployed is if they are gainfully employed, the company has to hold an equal position for them upon return … however, I have heard stories of military personnel coming back from deployment and the only equal position is in another state.

Somewhat similar to FMLA actually… the company is only required to hold an open slot for the person out on leave but WHERE that position resides becomes the tipping point learn more here again, this is my limited experience — others more knowledgeable might want to chime in.
