All Augment Triumphs in Destiny 2 work broadly the same way. First, you need to purchase the Braytech Transponder item from Variks on Europa. This is on the second page of his inventory (use the D-Pad to switch pages) and requires 50 Herealways Pieces to purchase. If you've yet to do any of his Sabotage objectives, the sooner you begin the better - as each one introduces additional ways for these resources to drop when defeating enemies throughout Europa. Once you have a Braytech Transponder, you'll be given a buff, the Braytech Signal, which will last seven days. Then, it's time to find a specific Fallen enemy, the Techno Squad Leader.
