- This is 1.5 patch and i've not seen anything serious. Beside, Ranger Team & ACU both using the same air rifle but one is for cure, the other is transquilize this is quite hard to understand ?! Both type are making the same noise level why? THey should have pros & cons, i suggest to put more features to this (Ex: ACU quick & fast but noisy and limited, Ranger team can do a lots of other task, quite but slow & vulrable). This is my ideas to prove those things are importance tools why managing!!
