The CTS Scope is the equivalent of the ACOG scopes in its predecessors. It is an attachment that can be attached on all assault rifles and sniper rifles. They have a 4x zoom of the target, which makes this scope effective for medium~long range combat. It is not recommended for close-range combat, for the zoom can slow down reaction and aiming speed. Therefore when in close combat, it is best to use hip-firing mode or other sights like Red Dot Sights or Holographic Sights.
Along with the Tactical Holo, the CTS has a special feature. When aimed at an enemy, the enemy is visible as a red dot on the map for all players of your team. This effect only occurs when there are no objects between the player and the target, and lasts for three seconds. This feature is especially useful if the player has Integrated Radar equipped, so the player can see where the enemy has gone through walls.
The CTS Scope reappears in MC5. It is a scope available for sniper rifles featuring 4X zoom, the same as that of the Aim ACOG. While the short range of the CTS compared to other sniper scopes may be a disadvantage at long-range sniping, it makes close-mid range engagements more viable with using sniper rifles.
