Dark Angels - Fire Support Squads: Without the aid of the Fire Support Squads, most Space Marine strike forces would swiftly grind to a halt. These units provide covering fire for their battleline and close support brethren, allowing them to better carry out their vital roles, while thinning out the enemy's infantry and eliminating their toughest armoured threats.These squads include the following:Hellblaster Squads - The Hellblaster Squads harken back to days of glorious legend, when entire squads of the Ist Legion marched to war bearing deadly plasma weaponry. Each member of a Hellblaster Squad bears some variant of the Plasma Incinerator -- a weapon whose fire burns with the heat of a sun. Deployed at the right place and time, such a squad can crack open an enemy battle line, blunt a foe's armoured spearhead or fell the most hulking of xenos creatures. Not even the thickest armour plating can withstand such tremendous plasma blasts for long. Although all members of a Hellblaster Squad bear some form of a Plasma Incinerator, they are nonetheless strategically versatile. The assault variant sacrifices a little range for its ability to fire multiple blasts. Both it and the standard Plasma Incinerator are light enough to be fired on the move, while retaining enough stopping power to turn a Greenskin mob of Killa Kans into glowing heaps of molten slag. The most powerful version of the armament is the Heavy Plasma Incinerator, which can fire at longer range, and its incandescent bolts of plasma strike with more power still. A Hellblaster with such a weapon must remain stationary if they wish to direct the formidable shot, but is able to hunt larger prey. All variants of the Plasma Incinerator can be supercharged. With a blazing roar, each weapon glows dangerously hot before discharging plasma bolts of extraordinary force. Typically this is done only in the direst of circumstances; like all Imperial plasma armaments, the weapons suffer from potential meltdown when set in this manner. While the Unforgiven are not afraid to martyr themselves in a starburst of self-immolation, they will only do so if such an act is justified by the situation at hand. As they have done since they first claimed The Rock as their homeworld, the Dark Angels honour those brethren who suffer a fiery death due to plasma overloads. Their names are chiselled into the Pillars of Conflagratus that line the Hall of Fire. They stand as a hallowed and eternal reminder to the living that no cost is too high to pay for victory.Devastator Squads - The members of Devastator Squads are the most heavily armed of all Dark Angels Space Marines. Enemy battle tanks are reduced to blazing wrecks before them, while towering walkers are blasted apart by their overwhelming firestorm. In addition to targeting armoured vehicles and providing support to advancing battleline or close support troops, Devastator Squads are ideal for cracking open enemy fortifications. A Devastator Squad commonly carries four heavy weapons, the exact nature of which varies from engagement to engagement, with anti-tank Lascannons and Multi-Meltas exchanged for infantry-shredding Heavy Bolters and Plasma Cannons as the battle requires. Traditionally, a Devastator Squad will wield a mix of weaponry in order to more readily adapt to the battle's challenges, although some commanders prefer a homogeneous weapons loadout, purposefully equipping their Devastator Squads to compensate for shortfalls elsewhere in the strike force. Any Devastator battle-brothers not equipped with heavy weaponry carry Boltguns, acting as spotters and providing covering fire, making their squad, in essence, a heavy Tactical Squad that is capable of dealing with a variety of threats. A Devastator Squad is at its deadliest when it can fight from a defensible position that overlooks the battlefield. Once entrenched in such a site they can dominate the foe, forcing them to either keep their heads down or be destroyed -- a situation that allows the Dark Angels to seize the initiative.Aggressor Squads - "Advance and destroy" is the directive that the Unforgiven Chapters have put in place for their Aggressor Squads. Each of these Primaris Marines is clad in heavy Mark X Gravis Power Armour and equipped with a pair of gauntlet-mounted weapons, turning them into a walking bastion of firepower. An Aggressor Squad can wade into the largest of enemy hordes, plug breaches in defensive lines, or lead the advance across open terrain. During the battles upon Mordian, the Dark Angels Aggressor Squads were pivotal in clearing the dense hive cities of foes, leading a slow, but inexorable advance hab-block by hab-block. Aggressor Squads have proven effective in many different deployment positions, although one of the most common is advancing between two formations of Intercessors. Armed with Boltstorm Gauntlets, an Aggressor Squad can spray wide volleys of explosive bolts, mowing down waves of enemy infantry. Back-mounted Fragstorm Grenade Launchers add to the carnage, blasting holes into oncoming formations with great blossoms of shrapnel-filled explosives. Should any foes live through such a hurricane of firepower, they are met by swinging Power Fists, each blow able to crumple a battle tank. Other Aggressor Squads are equipped with Flamestorm Gauntlets, allowing them to send fiery bursts outwards in searing sheets. This is certain death for tightly-packed enemies, or for cowardly foes that thought to take refuge behind thick cover or in bunkers. In the wake of such a firestorm, nothing remains of their enemies save brittle and blackened bones, and these are soon crunched to powder as the Aggressor Squads stride forward to bring their next target into range.Eliminator Squads - An Eliminator Squad is composed of dedicated marksmen. These fire support Primaris Vanguard Marines haunt the shadows of the battlefield, seeking out high-value targets and bringing them down with pinpoint volleys of bolt rounds.Suppressor Squads - Suppressors are a type of fire support Vanguard Space Marine and usually members of a Suppressor Squad. Suppressors are Primaris Space Marines who specialise in rapid responses to heavily armoured enemy threats, entering battle either by dropping directly into the action via the Grav-Chutes or in long leaps using the Jump Packs integrated into their Mark X Omnis Power Armour. As soon as a target is sighted, the Suppressors engage their shock-absorbing servo plates and let fly with their portable Accelerator Autocannons. The brutal ferocity of the foot-long, armour-piercing shells they unleash will blast apart anyone caught in their path and force even the most stoic enemies to seek shelter from the murderous firestorm.Eradicator - An Eradicator is a Primaris Space Marine dedicated to a close range fire support role, particularly against enemy armour and fortified positions. Before the molten ire of an Eradicator Squad's thermal ray Melta Weapons, heavy armour and static defensive positions stand little chance. Eradicators wear the heavier Mark X Gravis Power Armour pattern, allowing them to stride unharmed through waves of incoming fire before bringing their own destructive weaponry to bear at close range.Desolation Squad - A Desolation Squad is a squad of Primaris Space Marines who have been outfitted with multiple different types of missile launchers to provide long-ranged fire support to their battleline and close support brethren. These power armour-clad fire support specialists are an addition to the ranks of the Primaris Marines, laying down volleys of heavy firepower from across the battlefield. While Eradicators are forced to hustle their Melta Rifles into spitting distance, and Hellblasters must lug their Plasma Incinerators close enough for rapid fire, Desolation Marines can simply sit back and unleash a hellstorm of explosions. Traditional missile launchers -- such as those available to the Astra Militarum -- trade raw power for flexibility, swapping out Frag and Krak Missile payloads mid-battle. The armourers of the Indomitus Crusade will brook no such compromise, so these new rocket weapons are specialised to fire one of two warheads. In exchange, they boast the most powerful missiles ever available to Space Marine infantry. More reliable, more powerful, and with an effective range that exceeds even a Sniper Rifle, the Superfrag Rocket Launcher is the ultimate anti-infantry weapon and a decisive rebuttal to hordes of unwashed Heretics and slavering aliens. There is nothing quite like reducing the enemy's battleline to a smouldering crater with one pull of a trigger. On the other hand, when the Adeptus Astartes' foes rumbles towards them with a spearhead of hulking, armoured behemoths, a volley from a Superkrak Rocket Launcher will punch cleanly through any armoured shell -- be it metal or chitin. Whichever means of destruction chosen by the squad, Desolation Marines all pack a little something extra under the barrel of their rocket launchers. The belt-fed Castellan Launcher can saturate the sky with guided bomblets that rain down on the enemy wherever they hide. It is the perfect weapon for flushing out cowardly targets -- and it fires separately from a Desolation Marine's main rockets, allowing them to pick and choose their targets.Infernus Squad - An Infernus Squad is a squad of Primaris Space Marines deployed to provide close-ranged fire support to allied forces through the use of Pyreblaster Flamer weapons.  When an Imperial Space Marine force is faced with innumerable hordes of xenos, such as a Tyranid swarm or an assault by Ork Boyz, an Infernus Squad is the perfect tool. Armed with Pyreblasters that spit gouts of promethium-fuelled incandescent flame, they purge their foes with fiery wrath.
