Heavy Orbital Insertion Pod

The Heavy Orbital Insertion Pod is a larger variant of the standard single-occupant Orbital Insertion Pod, which deploys troops in the pod from ships low orbit into the battle zone. It operates similarly to the standard Insertion Pod, but has the capacity to drop at least three Jiralhanae into battle.

Overview
The Heavy Orbital Insertion Pod is the larger version of the standard Orbital Insertion Pod. It has a pyramidal shape, with a large hatch on each of the three sides. The pod most likely drops from ships, and freefalls through the atmosphere the same way the standard version does. It appears that when the Heavy Orbital Insertion Pod is nearing the ground, it fires three engines which are in the corners on the bottom of the pod to slow it down. The engines continue to slow the pod, until it reaches the ground. The hatches on the three sides of the pod start to open when the pod is several meters above ground. This variant is used by the Covenant to get troops, and possibly small vehicles, to the ground faster and in greater numbers. It was first sighted during the Fall of Reach, but possibly used in other battles.

Trivia

 * The Heavy Orbital Insertion Pod was first seen in the Halo: Reach Welcome to Firefight 2.0 Trailer.
 * It is possible that it is not dropped from ships in low orbit, but dropships that fly over.
