How does the scanning plug on MGS4 work?

Question

i scanned someone with it but it didnt do anything :S

Answer 1

It only has use in MGO, in MGO you can inject this into someone on the opposite team and after doing so DON"T kill them but just knock them out. If you kill the person it will have no value. Eventually they'll wake up and if they activate SOP with another one of their team mates you'll be able to see where the enemy team is. You can only use it with the CQC and the scanning plug skill equipped though.
