Swimming in the kool-aid, but don't know the flavor.

Sometimes heard in military circles, the phrase denotes someone who is overly-involved but doesn't really know what is going involved.

Usually used to point out a micro-manager who misses the forest for the trees.

Upon seeing a clueless officer trying (and failing) to prepare a Rifle-Launched Grappling Hook for use (not his job), a soldier might state to another, "Man, the LT is Swimming in the kool-aid, but don't know the flavor."

Variations include "All up in my kool-aid, and don't know the mix", or the abbreviated "Swimming in it."
