Covenant drop pod
From Halopedia, the Halo wiki
Summary
When the Covenant decide to capture a planet rather than simply glassing it from orbit, they use orbital insertion pods to drop Elites to the planet’s surface as shock troops. Use of these pods is very hazardous and is reserved only for critcal situations, or when a surprise attack is necessary. It is theorized that the pods are coated with an energy shield to disperse heat and are armored to withstand anti-air flak cannon fire. The vaugely coffin-shaped pods are small and cramped, with barely enough room for one Elite and his weapon, and there appear to be no restraints or other devices inside. Upon landing, the front of the pod blows off to allow exit, so the fronts are probably placed on the pod just before the drop.
These pods were evident around New Mombasa during The First Battle of Earth. They also appear in the level Uprising as several allies aid the Arbiter
It is proposed that these pods are a Covenant spinoff of the Human Entry Vehicles (HEV)'s used by the ODST's, more commonly known as helljumpers.
