The immortal agents of the enemy (Phantom Doctrine)

The mission where my base is uncovered, all that was taken, but it is necessary to evacuate the remaining people. I have three Opera left. Forwards 2 agents and a lot of fighters SEC and policemen. Now, I mess to restart this mission. Agents of the enemy, I was a Pushover and someone else, some immortal, Mumbler with 1 health, it becomes invulnerable just a bitch. In it, no one enters, three of the Opera at the 2-3 moves only work on it. No one will get! The emphasis came, Italica strelyal, were caught when not behind cover. All the past! While the cops and the SEC will fine. This is a feature that the type should not kill them, as they (the two agents of the enemy) then I will have to catch separately, or what?
