Elysian Drop Troops - Notable Elysian Drop Troops Regiments: 1st Elysian Drop Troops Regiment - This Elysian Regiment is a part of Ultima Segmentum's strategic reserve of Imperial Guard Regiments waiting for rapid deployment against any emerging threat to the Imperium. The vaunted 1st Elysian Regiment has a long and glorious tradition, having fought in the Emperor's cause across the galaxy; including having fought against heretic rebellions around the Eye of Terror, the Orks of WAAAGH! Urgok and Eldar pirates in the Barbarius Sector.9th Elysian Drop Troops Regiment - Participated in the Veridian Prime Campaign, against the Tyranids of Hive Fleet Kraken.12th Elysian Drop Troops Regiment - Fought in the Third War for Armageddon.13th Elysian  Drop Troops Regiment, "Helldivers" - The Elysian 13th Drop Troops have gained something of a heroic reputation amongst the regiments of the Spinward Front, having emerged from seemingly impossible odds on multiple occasions. Dubbed the "Helldivers" for their tendency to descend upon the enemy from above and leave destruction in their wake, the Elysian 13th are the subject of overblown tales and flights of fancy amongst the masses. The Departmento Munitorum has only encouraged this tendency, reporting whenever possible the victories of the 13th publicly, along with those of the other Imperial Guard regiments whose exploits will bolster morale. The truth is, as always, both more and less than the fictions wrought from it. Colonel Johanna van Meer, the regiment’s commander, is daring, optimistic, courageous, and more than a little vainglorious. Her fervour for the glory of battle has seen the Elysian 13th deployed to the deadliest of conflicts and the most challenging of missions, succeeding at any cost, and to great acclaim. The Helldivers have suffered great casualties over the years, and only a handful of companies of their original ten thousand warriors still remain, though each is a veteran of many battles. Only on one occasion have the Helldivers been reinforced with the remnants of another regiment. After the failed invasion of Avitohol, they bolstered their diminishing numbers with the remains of the Elysian 227th Drop Troops, though subsequent campaigns have reduced their numbers further.15th Elysian Drop Troops Regiment - Participated in the Yarant II Campaign.16th Elysian Drop Troops Regiment - Participated in the defence of Cadia during the 13th Black Crusade.22nd Elysian Drop Troops Regiment - Participated in the Yarant III Campaign, the Skopios Incident and the Cathalin Crusade.23rd Elysian Drop Troops Regiment - The 23rd Regiment formed part of the Imperial Taros Expeditionary Force to combat Tau aggression which had seen those duplicitous aliens seize that mineral-rich mining world. The regiment's part of the campaign was codenamed "Operation Comet" aimed at capturing and holding the planet's largest water processing plant. The 23rd Regiment also took part in the assault on Fort Moros and were awarded a regimental citation for their actions. During the desert battles of the Taros Campaign the 23rd Elysian Regiment was wiped out in the battle for Hydro-Processing Plant 23-20 by Tau forces during Operation Comet when they were surrounded and cut off three days after initially capturing the plant.41st Elysian Drop Troops Regiment, the "Angel Guard" - Participated in the 13th Black Crusade.158th, 101st, and 16th Elysian Drop Troops Regiments - All of these Elysian Regiments participated jointly in the 13th Black Crusade.64th Elysian Drop Troops Regiment - The 64th Elysian Regiment was wiped out during the Ill-fated Fifth Ymgarl Insertion.72nd Elysian Storm Troopers - Destroyed in combat against the Word Bearers Traitor Legion on Tanakreg.89th Elysian Drop Troops Regiment - Fought an Ork WAAAGH! on Elysia itself during an Ork assault.99th Elysian Drop Troops Regiment/Detachment D-99 - Fought against the Tyranids of Hive Fleet Kraken; the 99th Regiment made repeated combat drops in the defence of the Imperial planets of Moloch, Hamman's World and Moran.

The regiment's arrival proved insufficient to stem the tide of the Chaos force's advance. The 158th was almost destroyed in heavy fighting before St. Josmane's Hope itself was destroyed to prevent it from falling into the enemy's hands.181st Elysian Drop Troops Regiment - This regiment was diverted from the defence of the Forsarr Sector against the encroachment of the Ork WAAAGH!

The regiment was all but annihilated in the attack.234th Elysian Drop Troops Regiment - During the 12th Black Crusade, the 234th Elysian led a suicidal boarding action that resulted in the destruction of the Hades-class Heavy Crusier Injustice.

Unconfirmed reports indicate the drop regiments encountered a giant serpent-bodied creature that annihilated anything deployed against it. The description fits the known form of the Daemon Primarch Fulgrim, indicating that the Daemon Primarchs may be taking to the field for the first time since the Horus Heresy ended.
