Wiretap is an Awareness perk introduced in Call of Duty: Ghosts. It allows the player to use enemy SAT COMs as if they were on the friendly team. The SAT COMs will stack up with each other as long as the player's team already have a friendly SAT COM on the ground; if the player's team has only one SAT COM, but the enemy has three, the player using this perk will gain the "Advanced UAV" effect from all four SAT COMs. It will work in Hardcore as long as there is at least one SAT COM anywhere on the ground. It costs nine squad points to buy.
When playing in Free for All, the SAT COMs effects will be enhanced, i.e. one SAT COM gives a UAV, two gives a faster UAV and three gives an Advanced UAV.
