Secret Service

If those guys weren't so busy, I bet one of them could help me. The Secret Service is the president's official bodyguard team. Although they specifically guard the president, their character model has been used for other characters who do guard-related jobs. There are dozens of them, and they all look exactly the same.

Physical appearance
The Secret Service agents are all adult male aardvarks wearing blue suits, white shirts, and blue ties. They also wear sunglasses and an earpiece communicator.
