This is my own Imperial Guard regiment their name is german for "Frozen Marksmen". This particular guardsman of the regiment is armed with a Dwimlicht Meltagun which works like a pump-action shotgun also instead of a solid focused beam it is a cone or plum of intense heat. So think of this variant as a heat-ray shotgun lol x). I created this regiment for my Only War game I am working ;) the players will be apart of this regiment.

As for their uniforms I tried for a mix of WW2 German Wehrmacht/Civil War designed for winter warfare for extreme temperatures. For COs they have a mixture of Regimental Dress into their uniforms with unquie helmets that are inspired by the France Guard Dragoon of 1806 and the Austria Deutschmeister Regt. 1805. :)

Now for some info on the Regiment :3

Where is this Regiment from?
This Imperial Guard regiment hails from the gas giant Dwimlicht, known as super gas giant as its size is equal to 80 Jupiter masses with a Osmium-Nickel core. It has been labelled as a ice giant, with a Selenium Radon rich atmosphere from the cloud tops down to about 60% of Dwimlichts radius. Below this, Dwimlicht is predominantly "icy", i.e. consist mostly of water, methane, ammonia, and bromine. There is also some rock and gas, but various proportions of ice/rock/gas could mimic pure ice, so the exact proportions are unknown. As most temperatures are below -458.15 degrees Celsius at these supposed "crust" of Dwimlicht. The population of Dwimlicht lives in the upper atmosphere in ancient hovering installations from the Dark Age of Technology, theses installations wore built by mankind's lost past. As far as Dwimlicht techpriests have learned the purpose of this installation is to process the frigid crust interior into a breathable atmosphere for the inhabitants. While it also can harvest and covert the Selenium Radon oxide in the atmosphere into a form of starship fuel that yields faster travel between solar systems. Most of the population from Dwimlicht tends to be circumspect, hard-working, stubborn, with a strong sense of duty and somewhat pessimistic.

Why was the Regiment raised?
The Dwimlicht Regiment was created to support the war in the Hrakian Sector, which provides ground troop fire support and heavy weapon support in crucial critical locations to hold for the Imperium. The are wildy known as excellent marksmen and soldiers with excellent forsight, considering their options and plan accordingly even during the heat of battle. Their unique homeworld has garned much attention from the Adeptus Mechanicus, as such they have developed a close tie to the organization. They allow the techpriest access to forgotten tech of their world in exchange for agumetics and more specialized weaponry. Right now there are only 25,000 in number of the Dwimlicht regiment, but the are assigned to critical warzones in need of their skills. Hrakian Crusade is a large conflict that started with the world of Rylk V when it declared its independence from the Imperium and pledged its alliegance to the Forces of Chaos. This increasing amount of warfare as brought other factions into this conflict Orks from the Waagghh! Grimcog, a greedy salvage obessed Big Mek seeking to built more and more strange war machines and contraptions. While forces from the The Cleaved come at the aid to the Rylkian Milita under the command of Sorcerer Lord Acheron with his fanatical and well-trained "oath-bound" heretics. But a ancient flagship of the Imperium as reappeared near the edge of the sector, it was the lost Saint Castillina's Cathedral. A powerful ship in its own right equipped with power lance weaponry long since forgotten, The Imperial Guard send a small detachment of Dwimlicht guard to reclaim it for the God-Emperor. But at the same time the Ork Big Mek and the Sorcerer Lord have their eyes on it too...
