The Napalm grenade was a type of incendiary grenade used by UNSC forces during 2552. They were used by Colonel James Ackerson in testing the MJOLNIR Mark V armor on Reach, hidden amongst the Pillars of Loki and used in conjunction with Sonic grenades.[1]


Napalm was developed by the United States of America during World War II. It is a mixture of chemicals which, when mixed with gasoline and compressed, makes a sticky incendiary gel. The name is a combination of its original ingredient's names: aluminum salts of naphthenic and palmitic acids. The name has since evolved to mean any substance that causes intense fires upon ignition.

  • In Power Net, it does very little damage to the power cores and so it is better used on enemies.
