Combat support vehicle
From Halopedia, the Halo wiki
The Combat Support vehicle is described as resembling a giant barrel-bodied beetle with a bulbous head. The vehicle also has struts when it is ready to set down and deploy what is inside its cargo compartment. The side doors fold outward along the length of the vehicle like clamshells. Aside from the driver, the cargo compartment is capable of holding twenty infantry personnel.
In the year 2526, during the Human-Covenant War, Blue Team encountered these vehicles on the planet Mesra. The Covenant deployed fifty of these vehicles to carry twenty Drones each in a strike against the UNSC and allied forces.
