Here's mine:
Just finished my Blood Angel army, here's pictures and background for it
The Wing Striker strike force was composed by the late Captain Haftrion of the 3rd Company. The strike force would be in two attack waves which work in concert together or can work as a single force. The 3rd company is split into two forces; one mechanised in Razorbacks with Vindicator support and the other half using jump packs.
The Razorback force would be the vanguard of the force seeking out enemy armoured forces which the Razorbacks would lay down a torrent of lascannon fire forming the "strike" part of the force. The second part of the force, the "wing" will deep strike from Thunderhawk transports attacking enemy infantry which have been blown out their transports or focus on armoured targets with melta weaponry which lascannons cannot deal with at range.
With the enemy occupied with the deep striking Assault Squads the Razorbacks can move forward unleashing a torrent of fire from the Razorbacks and Vindicators, the Assault Squads will disembark from the Razorbacks to support their battle brothers already engaged in combat.
The above strike pattern is not always feasible against a particular foe such as Tyranids or Orks which can easily take advantage of the arriving Assault Squads from Thunderhawk transporter and swamp them. In this case tactics are changed which the jump pack aided squads will keep cover behind a wall of Blood Angel armour as the Razorbacks and Vindicators use the lucifer pattern engines to cover ground quickly while laying down supressing fire. Once the armour is within range for the enemy to launch an assault, the battle brothers using jump packs will launch a counter assault leaping from behind the Razorbacks slaughtering the foe in a melee, battle brothers from the Razorbacks will engage to support the units using jump packs if required.
Captain Haftrion himself was killed by a warband of Iron Warriors several hundred years ago. Librarian Varios was assigned to command the 3rd Company and as of yet a replacement Captain has not been named. The 3rd Company has been split dividing the strike formation, Librarian Varios leads the armoured porition of the force and has claimed revenger on the Iron Warriors and erdicated the warband in recent years. The other half of the 3rd Company has been assigned to deal with a small bioship of Hive Fleet Kraken which has been slowly harvesting small worlds and gathering strength. It has been heard this portion of the 3rd Company was destroyed by the Tyranids on the planet of Howsayyer but this has yet to be confirmed.
Librarian Varios has attached several other Librarians to the 3rd Company under his command, though Varios is the highest ranking Librarian almost at epistolary level. Librarian Judis leads the armoured force of the 3rd Company with Varios while two other Librarians lead the battle brothers using jump packs. Both Varios and Judis have selected battle brothers from the 3rd Company to form two Honour Guard squads. Honour Guard Varios prefers to use meltaguns for armoured destruction leading from the front and as a visible anchor point for forces attacking enemy armour, or monstrous creatures. Honour Guard Judies favours flamers using these to clear ground and infantry formations and then moving into close combat.
Squad Artico is joined with Priest Solomon who is keeping a watchful eye over battle brother Sarkis who has shown promise as a future Sanguinary Priest. Even though currently a battle brother, Sarkis will assist Solomon on the battle field with wounded battle brothers, it won't be long before Sarkis joins the ranks of Priest hood. Sgt Artico has severed with the 3rd Company for two hundred years, he's more machine than man now thanks to a Carnifex attack durnig the Battle for Jericho campaign which saw Artico take a direct hit from bio plasma melting his armour destroying his legs and injurying his face, though Artico crawled up to the distracted beast and rammed his power sword through the animals jaw right through it's brain and out the other side of its head killing it out right.
Squads Arjenko and Forlax; Arjenko himself has recently been promoted to Sgt while Forlax is part of the 1st Company and either is usually boarding Space Hulks in Terminator armour or sometimes is part of Vanguard Veteran squads. When not required by the 1st company Forlax while assist the 3rd Company his tactical knowledge spanning three hundred years proving invaluble.
Squads Deviss and Serra, Sgt Deviss has been awarded the iron halo for extreme bravey which Lord Commander Dante himself was struck down by a powerful Ork Warlord. Deviss launched a one man assault against the giant Ork severing the beasts hand and allowing enough time for Dante to gather himself. With the combined might of Dante and Deviss the Ork Warlord was killed in combat and the Waaagh! halted. If it wasn't for Deviss charging into battle then Commander Dante certainly would have been on the Warlords trophy rack.
Sgt Serra is a veteran Adeptus Astartes serving the Blood Angels for seven hundred and fifty years. He is part of the 1st Company and drafted into the 3rd Company when required.
Librarian Judis armed with the Blade of Angelus, a anicent force weapon rumoured to be constructed by Sanguinus himself. This blade was given to Judis as a sign of respect from Librarian Mephiston himself when Librarian Judis saved Mephiston from certain death.
Vindicators Vitae and Divine II have been attached to the company since the former Captain formed the strike force.
Sgt Vorro part of the 1st Company prefers to use two close combat weapons instead of ranged fire power, armed with a gifted power weapon and his original chain sword Vorro lays waste to all those oppose him. It's suggested Vorro prefers dual combat weapons as in the 1st Company Vorro is part of a Assault Terminator squad and armed with lightning claws.
