Something biological where it would slowly kill the enemys who are exposed. Also a 5 killstreak you can call in a MQ-9 Reaper which carries 4 hellfire missile where they are used at your disposel. You would lase a target for it then it would fire within seconds. It would be nice for a domination type gameplay. Also its not as easy to shoot down like a UAV
