Army’s Heaven is the secret organization founded by Gene in Metal Gear Solid: Portable Ops.
Portable Ops follows Naked Snake after the events of Metal Gear Solid 3 and centers on a revolt within a fictional Soviet military setting. Gene, the game’s principal antagonist, develops a plan involving a military force known as Army’s Heaven.
The organization is distinct from the Patriots, the secret governing network explored in later games, and from Cipher, the intelligence organization linked to Zero. Philanthropy is an anti-Metal Gear group associated with Otacon and Solid Snake in Metal Gear Solid 2 and Metal Gear Solid 4.
Army’s Heaven reflects Gene’s belief that soldiers should create a state independent of civilian political control. Portable Ops therefore uses the organization to explore the series’ recurring conflict between military autonomy, ideology, and the consequences of manipulating soldiers.
