The '''M6634/Defoliant Projector''', also referred to as the '''6634 DS''',{{Ref|''[[Halo Encyclopedia (2009 edition)|Halo Encyclopedia]]'', section "UNSC Weapons", page 320 (2011 edition)|Id=Enc}} is a flamethrower that was in service with the [[UNSC Marine Corps]], particularly its [[Hellbringers|Hellbringer]] divisions, during the early years of the [[Human-Covenant War]].{{Ref/Reuse|EVG}} Most notably, the weapon was used by troops of the {{UNSCShip|Spirit of Fire}} in [[2531]], during the [[Harvest campaign]], [[Battle for Arcadia]] and [[Battle of Trove]].{{Ref/Reuse|HWCamp}} The weapon is a variant of the [[NA4 flamethrower|NA4/Defoliant Projector]].{{Ref/Reuse|Prima}}{{Ref/Note|Most sources refer to this weapon as simply "the NA4". However, the ''[[Halo Wars: Official Strategy Guide]]'' identifies it specifically as the M6634/Defoliant Projector, and a later model of flamethrower called the M7057/Defoliant Projector was identified as a variation of the NA4 too, this time by ''[[Halo: The Essential Visual Guide]]''. Consequently, this page treats the M6634 as one of multiple NA4 variants in existence.}}

By 2531, the [[Hellbringers|Hellbringer]] complement of the {{UNSCShip|Spirit of Fire}} had been outfitted with these weapons.{{Ref/Reuse|Prima}} In February of that year, these soldiers would be deployed against the [[Covenant]] on the surface of [[Harvest]] and later [[Arcadia]]. The weapon would also see its first use against the [[Flood]] in this month, when the ''Spirit of Fire'' pursued a Covenant vessel deep into uncharted space and encountered the parasite on the artificial [[shield world]] known as [[Trove]].{{Ref/Reuse|HWCamp}}

{{Quote|I tell ya, these things sure beat the old NA4 models...|Unnamed Hellbringer{{Ref/Site|D=01|M=6|Y=2020|URL=https://youtu.be/A04ZmY2UHgU?t=35|Site=YouTube|Page=Halo Wars 2 All Hellbringer Quotes|Id=HW2Quotes}}}}

During the [[Second Ark Conflict]] in [[2559]], a number of Hellbringers on the ''Spirit of Fire'' used the more portable M7057 model.{{Ref/Game|HW2|Hellbringer unit}} This new model of NA4 was noted as being a significant improvement over "the old NA4 models", likely in reference to the M6634 which had been used by the ''Spirit of Fire''{{'}}s Hellbringer complement previously.{{Ref/Reuse|HW2Quotes}}

In ''Halo Wars'', the M6634 flamethrower is the primary weapon of the Hellbringer unit.{{Ref/Game|HW|Hellbringer unit|Id=HWUnit}} It excels in an anti-infantry role, able to kill enemy units with relative ease, and is also useful for destroying enemy buildings. However, it is essentially useless against enemy vehicle and air units, and it has a very short range.{{Ref/Reuse|Prima}}
