I was leading a small squad of about 7 people. For the most part we were kicking as taking names, so to speak, against the masses of the enemy, but as we were attacking a base our scout reported another organized group of about 10 people guarding the control console we needed to capture. Despite being invisible, he was killed immediately. This was trouble. I had my squad crouch, hidden, in the strategically useless "map room" while we pondered what to do. But our enemies were obviously fans of teamwork, so I had an Idea. I looked at the "so and so killed [my scout]" message to get the name of the enemy soldier who killed him. I sent him a private message reading:
"Hey, can I join your squad?"
As expected, the guy who killed my scout was not the enemy squad leader, and thus unable to invite people to the squad, and, as was customary in that game, he simply referred me to the player who was. So I sent that guy a private message:
"Look out, MAX unit headed your way!"
Then I had the dead scout respawn as a "MAX unit" and rush the control console. Again, he was killed immediately, and I received a message from the enemy squad leader:
So then I sent him another message:
"Look out again! Huge enemy squad headed for the generator!"
Again, I had my poor scout respawn, and sent him to go shoot the generator a couple of times so that the "Your generator is under attack!" message would play for the enemy. As soon as it did, the enemy leader replied again:
"We'll take care of it, thanks!"
Then most of the enemy squad rushed off past us toward the basement, leaving only 2 people guarding the Control console. We walked in and killed them, then placed a number of explosive mines just inside the door, and ran back to our safe spot. The rest of the enemy squad came rushing back, and as soon as they were all inside...
In deference to his selfless service, I had the scout press the detonator. Then, with the advantage of cover, we were able to hold the control console and capture the base. Best of all, after we'd taken the control console, I received another message from he enemy squad leader:
"Hey, my squad is reforming to take back the CC. You want to join us?"
It wasn't until I ended up personally killing him a half hour later that he realized my constant attempts to 'meet up' with him and offers to 'scout' for him were actually attempts to gather info on his plans and location. He really should have done a /who on me (which would revealed my team) before revealing sensitive info via private message.
