...when you give someone an explanation & it's still a mystery. =D An Rcxd, The Pegasus or AGM, The chosen-location airstrikes (brown missle avatar), The predator missile... any perk that makes you invisible... you stay invisible until it's timer runs out, then you come back- still invisible- for like 5 seconds. So you would need to know 1. At which location they "went into' this killstreak reward & 2. Then guess where they will reappear within a 5 second sprint radius of that location where they disappeared into the killstreak. Sometimes I will get an Rcxd then pruposely allow myself to be killed so I can earn a 2nd car. it's nice to have 2 or 3 cars for the end of a round, especially if your team is comprised of people that can't sit still during sudden death & like to die-off like flies during a cold snap.
