Medical director never has any objectives

[Tom Clancy's Gay Ghost]

Have the RD and MD objectives that have them hurt eachother, to keep the rivalry alive, like:
Break the MD's/RD's office.
Punch the MD/RD
Ensure the the other guy's office is unpowered at the end of the round.
Smoke the RD's weed.
Have the robuddies heckle the absolute heck out of the MD.
etc.

How about kidnapping the other's pet into your own locker?
