Destroyed 10 walls or floors in Swords of Sanghelios.
Swords of Sanghelios is full of destructible walls and floor panels. Destroy 10 of them across the mission - Ground Pound is the reliable tool for breakable floors, and Spartan Charge or explosives handle the cracked walls. They're common in the temple areas, so ten adds up fast if you deliberately smash through things rather than around them.
