40mm Tracker Cannon

 is a primary weapon in Titanfall 2.

Summary
The 40mm Tracker Cannon is a semi-automatic 40mm cannon that fires explosive rounds. When utilized by a Tone titan, each successive hit on a valid target adds an amount of partial-lock on for Tracker Rockets. Titan Kit can be used to allow 3 bullets to be stored when aiming down sight, which allows for a burst fire to occur. This can make it easier to lock onto enemy Titans.
