The '''NA4/Defoliant Projector'''{{Ref|'''[[Halo: The Essential Visual Guide]]''', ''page 69''|Id=EVG}} is a type of incendiary projector used by the [[UNSC Marine Corps]], primarily by the [[Hellbringers]]. It is a designation which encompasses at least three distinct weapons. 

==Variants==
===M6634/Defoliant Projector===
{{Main|M6634 flamethrower}}
The M6634 Defoliant Projector is a large weapon which fires a napalm defoliant, often fed to the weapon by an external tank carried on the user's back. It was often used by Hellbringers in the early years of the [[Human-Covenant War]], including at the [[Harvest campaign]], [[Battle for Arcadia]] and [[Battle of the Etran Harborage]]. The M6634 is compatible with the [[M301 grenade launcher]] attachment.{{Ref/Game|HW|[[campaign]]}}{{Ref|''[[Halo Wars: Official Strategy Guide]]'', chapter "Factions", section "Barracks Units"|Id=Prima}}

===M7057/Defoliant Projector===
{{Main|M7057 flamethrower}}
The M7057 Defoliant Projector is a somewhat smaller and more portable variant. Instead of napalm, the M7057 uses Pyrosene-V for ammunition, and has a gas tank located on the back of weapon rather than on the user's back. The M7057 is more decorative, with a face of a shark painted on the heat shroud. It saw use throughout the Human-Covenant War, particularly in its latter years.{{Ref/Reuse|EVG}}{{Ref|''[[Halo: Silent Storm]]'', chapter 10|Id=SSIJet}}

At least two versions of the M7057 exist. One of these has a nozzle which extends well beyond the heat shroud, and also has a large fuel tank protruding from the rear of the weapon, which can be removed and replaced on the battlefield to refill the weapon's fuel supply.{{Ref/Game|HPC|[[Halo: Combat Evolved Manual|manual]], page 13}} The second lacked this larger fuel tank, opting for a smaller one mounted just beneath the rear handle. Its nozzle was also much shorter, only barely extending beyond the heat shroud.{{Ref/Site|D=01|M=6|Y=2020|URL=http://halo.bungie.net/projects/halo3/content.aspx?link=h3flamethrower|Site=Bungie.net|Page=M7057 / Defoliant Projector|Id=BNet}}

====M705 Incendiary Jet Tool====
The M705 Incendiary Jet Tool, often nicknamed the "I-Jet", is a compact variant of the M7057 which is suitable for use in a vacuum. It is fed by a tank-pack, and uses self-oxidizing fuel. It existed in the early years of the Human-Covenant War.{{Ref/Reuse|SSIJet}}
