Phoenix Logs/UNSC Units/Flame Warthog

From Halopedia, the Halo wiki

Warthog armed with powerful flamer.

The Flame Warthog, or 'Flamehog', is an adapted Warthog only available to Morgan Kinsano. The usual Warthog autocannon has been replaced with a white-burning flamethrower which is particularly effective against infantry and buildings. The passenger also fires anti-air rockets.

The Flamehog has the same ramming ability as a regular Warthog and an upgrade allows the flamer to be replaced with a grenade launcher with incendiary grenades.
