Mission One
Setup
We spent several days adding modifications to our weapons, allowing them to be upgraded with technology found on the field. Many of the heretics on Terra had also been adapting their weapons, and the Tactica Imperialis states that to defeat ones' enemy one must first understand their ways of war. We had been flying around the region known as North America, gathering soldiers that had survived the initial fall. Two new rookies joined us, but neither was particularly notable. We got a vox call on day four though, a VIP had been located in the slums of Seattle, and we needed a strike team to drop in, and secure or kill the VIP. The squad was obvious.

MISSION REPORT ONE- OPERATION BLACK PARAMOUR

Amy Clarke, Medic, Squad Leader for Operation Black Paramour

The squad consisted of me, our heavy weapons specialist; Pepper, Yegor the Sharpshooter, and Gordons, a rookie. After kitting out, the Valkyrie trip was uneventful. As soon as we dropped in however, Yegor spotted a small guard team, a heretic captain and a drone, in one of the buildings near our target.
We approached silently, masking ourselves behind benches and walls in the breaking down slums. The first shot was fired by Gordons, hitting the heretic in the side of the head, killing him before he had a chance to respond. The rest of us gunned down the drone with overwatching fire.
Now that we had gone loud, we approached the VIP hastily, Gordons and I taking cover in the building with the VIP, and Yegor on an adjacent rooftop with Pepper.

We moved up, I spotted an enemy tower, and sent my drone out to hack into it. After a second or two though, it became evident that I had failed somewhere along the line, and my drone was ejected by the machine spirits inside, which then called in another Valkyrie full of heretics and mutants.
Yegor moved forth to get a better vantage point, but in doing so alerted a pair of mutants to our location. We now had two psykers, a heretical captain and two more heretics to deal with, as well as a drone.

The drone stunned Gordons, and I was disoriented by one of their psykers warp powers. When I came to, Yegor and Pepper were in a firefight with several of the enemies, and Pepper had taken a hit. One of the mutants was behind me, but it took a single blast from my shotgun to silence that threat.
The ensuing firefight was bloody, many foes were set on fire, or blasted apart with powerful weapons of the imperium. By the time the Valkyrie had returned, only a single heretic stood alive; surrounded by the corpses of his allies. He fired off a shot in desperation at Gordons, our rookie, but it hit, almost killing the poor boy. As the squad climbed the ropes into the Valkyrie I took him out. Nobody was lost today. Gordons had secured the VIP, and both Yegor and I earned a promotion for our valour, as well as the rookie being assigned as a weapons specialist.

Overview

Plot
This is the opening to the grimdark future of the forty first millenium. Mankind has been overrun by xenos, and the God-Emperor is missing, silent on his hidden throne. Alien scum has taken the system by force, and powerful blockades prevent any communications from calling for help. We will have to solve this ourselves.
Just before the invasion, the training regiment known as the Veulian 1st was stationed on Terra to be inspected by the Adeptus Terra itself, as a newly formed regiment from a recently colonised Hive World. The regiment was placed into a helicarrier, to be transported over, as the attack hit. Beams of light and plasma rained from the sky, destroying all but the most primitive weapons on board, and killing many staff and soldiers alike. Almost all of the regiment is ruined, some remain scattered on the planet below, but collecting them will take scrap and time, neither of which the Veulian 1st has.
8 soldiers survived, rookies and fools, the lot of them. We have a pilot, albeit not a very competent one, and an engineer, as well as a researcher, who'll be digging around in the armoury meant to fit a regiment for equipment that might suit a soldier.
The comms have gone silent, and in the time since the invasion the whole of Terra seems to have been pacified. Even for the 41st millenium, this looks bleak.

The regiment will have to fight a grueling, uphill battle against xenos and heretic alike, to shut down their foes once and for all, before a secret project is completed, that could mean doom for the God-Emperor, silent atop his throne. The remnants of this regiment may be Terra's last hope...


Rules
Mechanically speaking, I'm going to be playing on classic, ironman, with an arseton of mods, most of which are cosmetic, but some of which add a metric anus ton of classes to the game, allowing for fine tuning of the perfect squad. Many traits have also been added, such as being an urbanophile, or loving men or women, giving buffs when in squads with certain genders, or debuffs in terrains that the soldier dislikes. I intend to do 1-2 missions per post, keeping up with screenshots and descriptions of each mission, as well as the interesting conversations that occur in downtime as well. All of my soldiers are being given a regimental feel, and while some are more strict about the Tactica Imperialis than others, all are expected to hold to it at least in spirit. ADVENT are acting as heretics, and we are assuming that the Tau invaded, due to the numerous subservient xenos swarming around them. The first few posts will be written from the POV of the squad's current field leader, a sergeant named Gallus, until he presumably dies and the next field-leader takes up the mantle. After the introductory mission we have a medic, a gunner, a sniper, and a sergeant, as well as four redshirts. Missions that Gallus doesn't go on (because of injury or just bad team composition) will be recounted from the perspective of the acting leader then.


Playstyle
Strategically I am focusing on getting squad size upgrades ASAP, because as any guardsman knows, having five friends next to you is a damn sight better than having three, and offense is of course more valuable than defense, the life of a guardsman is, after all, wholly expendable.
An old story cited a Lord General being told that the planet he intended to take was so firmly held by the Tyranids that for every square foot of land gained, 8 guardsmen would die for it. He asked how quickly it would be done.

That is my playstyle for this campaign. Each soldier will do their best to survive mission to mission, but I will have no reservations about suicide missions if it's for the greater good of the regiment. Friendly fire, grenades being thrown into melee, some soldiers might have a lot to apologise for between missions.

Regardless, each page is going to come in the form of one or two mission reports, with appropriate slurs and exaggerations depending on the soldier telling the story. I don't expect this to last long.
