Light Capital Warship
From Halopedia, the Halo Wiki
The Light Capital Warship is the smallest warship classification in the UNSC, and the Covenant.
This class is the most common warship in both fleets. The UNSC light warships include the Mako-class Corvette, UNSC Frigate, Stealth Cruiser, and UNSC Destroyer, while the Covenant's light warships include the Covenant Frigate and Covenant Destroyer. Also, several Covenant cruisers (Covenant Light Cruiser, Covenant Cruiser and CAR-class) are very small compared to other Covenant ships, but they're not classified as light warships.
Some of the light Covenant vessels are smaller than their UNSC counterparts, but can still vaporize dozens of ships, despite their size.
