Two acronyms :

SMO - Support to Military Operations

(other meanings depending on context, but Support to Military Operations is a major NSA activity)

YRS - Yakima Research Station

(Official name of the Yakima, Washington state, collection site.)

OVSC - based on this and other information, I believe this stands for the [signals intelligence] OVerSight and Compliance training group.
