I had a fairly good LCS get killed.
It started as a drug cartel. Or, as they called it, a brownie cartel. They sold brownies, (like, a lot of them) to make money for La Revolution. But they didn't do a very good job hiding it. Police raided their headquarters and ended up killing everyone except the leader and 2 others, and the leader received a serious spinal injury.
With the safe house compromised along with all of the members and funds, the squad disbanded for around 10 years. For a while, their influence remained, but they were eventually forgotten, and the leader eventually recreated the Brownie Cartel. This was FancyPants McGee's Insurrection. He was once an unstoppable soldier, but in his current state he was incapable of fighting. He managed to convince many people skilled in the art of infiltration to join him. They ran their own newspaper. Eventually, they managed to sway the public opinion in an even greater way then they had before by breaking into radio stations and broadcasting their own shows which were fueled by McGee's astounding persuasiveness and charisma. A very large number of Liberals were put into congress later that year.
But then something terrible happened. An important sleeper broke, and ended up betraying the squad. He told them everything, and the safe house was raided by an extreme number of CCS members. Not a single liberal survived, not even McGee.
LCS, as you probably guessed. I'll probably post this story in Curses.
