Forerunner Lifepod

Forerunner Lifepods are fallen forerunner life pods which bonus the Covenant/UNSC by maximizing the army by 10 units. This could make the covenant population rise to 50 or 60 if they have the Followers upgrade. It rises the UNSC population to 40 or 50 if they have their population upgrade on.

Downsides
Even though it is wonderful to have 10 extra units in your army, the lifepod has downsides to it too. These are the following: Positives:
 * The Lifepod is guarded by Rebel Infantry and may be hard to capture.
 * Once you have taken it, people will want to take for their own goods so it is hard to defend.
 * Only one appears in Halo Wars on One map.
 * You may be invaded while attempting to capture the lifepod. Since it isn't a base, you can't use it to save yourself.
 * Increases your army size.
 * If playing as the Covenant you can create 3 Scarabs if you have the Followers upgrade.
 * Increases UNSC population to its highest possibility. 50 units.

Trivia

 * It is odd how it is called a Forerunner Lifepod as it looks very much like the UNSC Pillar of Autumn's lifepods seen on the missions Pillar of Autumn and Halo.
 * The Lifepod only appears on one map in Halo Wars.
 * It is one of the few forerunner structures not defended by Sentinels.
 * The only other forerunner structure not protected by Sentinels is the Forerunner Supply Elevator
 * When you enter the lifepod, much like the Sniper tower, the land around becomes clear.
 * The Rebels guarding it are the only rebels that aren't in a supply elevator not to use turrets against you.
