Buddyfucker 

One who will do anything to further his own personal interests without regard for the impact his actions will have on the interests of his "friends" or colleagues. Buddyfuckers cannot be trusted to "do the right thing" and have no regard for abstract principles such as ethics or morals.
This title is used frequently in the U.S. Naval Aviation community. When speaking discreetly, Aviators may say "buddy is only half of a word."

I can't believe Brad tried to steal my job just so he could get a bonus; he is such a buddyfucker!

Buddyfucker 

During the Vietnam War, and on until the mid 1980's, the term 'buddyfucker' referred to soldiers with the Military Occupation Specialty (MOS) 05G, Communications Security (or COMSEC) Specialist. COMSEC's job was to monitor friendly radio and telephone traffic for security weaknesses; the rumor started that they were looking for soldiers engaged in criminal activity. MOS 05G was replaced in 1985 by MOS 97G, Multi-Discipline Counter-Intelligence Operator/Analyst.

"Careful what you say on the phone; COMSEC could be listening in. Those buddyfuckers don't pay."

buddy fucker 

Anyone who ditches or lets their friend down, usually to do some generally undesirable task, especially if it is taking blame, exhausting work, getting in a fight. A buddy fucker usually takes a lot of blame from his friends, and depending on how bad the ditching was, may not be friends with the fucked buddy much longer.

Joe: You wanna fight?!
Bob: C'mon Jim, back me up here. *Notices Jim is gone and gets beaten up*

The next day...

Bob: Jim, you are such a buddy fucker. Asshole.
