The fire-team can easily kill you, but you can easily kill them. I almost died a few times by my own mistakes. The fire-team cannot split up and you need to stick with your support so he can soak up some dmg. You all run around like you need to complete the mission in 4 sec while alarms are triggered and you run glass cannon on 4 characters.
When I play fire team I run it like a squad knowing we can be killed at anytime. Its when the predator splits u up is when people end up getting killed or he get a 3 hit combistick throw. Either way stay close so if your downed the other fire-team members can make the predator drop the victim. If your leveling up weapons i get it. At least have one weapon for the predator. flashbangs and thermals work great.
Below is my vid on scout preds since they are not played much---- they are quiet but get the job done.
