"My directive wasn't to worry about you, neither to care for your safety." FourSev said, and shot the trooper who motioned for him to follow her a sharp glare. He stopped Major Zorra by stepping in front of her again, and handed her a communicator. 

"This communicator is tied to my frequency. I've transmitted the ideal route for the convoy to take onto it, and you may also use it to communicate with me. I will be shadowing the convoy from the rooftops, and will interfere with any problems should they arise, Major." He said, and walked off on his own. He stopped, and looked back. "I don't take orders from you, Major." he added, and continued.

Assuming that he would exit the base unabated, he would take position on the rooftop closest to the command center, and await for the convoy to leave, where he would stealthily follow it.
