333rd Cadian "Half-Damned"
Originally a standard Cadian Shock Troop Regiment, recent action on the planet of Veridianitia V forced a change of organization due to attrition. To combat the loss of men locals were recruited directly from the local PDF into the 333rd, with appropriate training in conventional guard tactics and equipment to follow pending the victorious conclusion of the campaign. This ad-hoc situation lasted for half a decade resulting in only half of the regiment being native Cadians. With the inclusion of so many Veridiantians to the regiment local traditions, such as the inclusion of Rough Rider squads and the presense of locally recruited Abhumans became standard regimental policy. Time has forced the regiment into a position were Abhuman recruitment has dropped off but until that time the abhumans remain a valuable inclusion in the fighting force.
Colonel Pelletier - The regimental leader that oversaw the ending 2 years of the Veridianitia campaign, Colonel Pelletier was instrumental in the successful integration of local men and tactics into the regiment. Many in Guard command argued that the locals should be excissed from the regiment but 5 years of combat duty had seen a total integration down to the squad level. In addition, many Cadians had displayed admiral skill with the local breed of horse and had risen to command some of the Rough Rider platoons within the regiment.
Focused more on tactics and logistics, Colonel Pelletier is less a warrior and more of an officer. Which isn't to say that he isn't capable in a fight. When in combat he is typically seen wielding his personal chainsword with both hands for maximum control while his personal force field shimmers around him, stopping most enemy attacks. Once immediate danger to himself is over, Colonel Pelletier returns to his command mindset, claiming he can 'see' the whole battle in his mind "If you fools would just let me concentrate." Repeated claims of this have reached high command and the Inquisition, tests revieled a complete lack of psychic talent.
Psyker Jones - Jack Jones is a native Veridianitian recruited to the regiment when Guard command cleared him for combat duty and rated his power at the Primaris level. Soft spoken and eager to help, the only sign that he's a psyker is his bad habbit of talking to unseen persons when in stressful situations, that and the fire he hurles at the enemy. Generally, he is attached to the Regimental command squad, performing Tarot readings to aid Colonel Pelletier in tactics.
Commissar Levelin - The sole surviving Commissar of the Veridianitia V campaign, Max Levelin has inherited a difficult job. Typicaly dispatched to the front line fighting to bolster moral, Levelin is one of the Cadians who has displayed skill in husbandry (horse craft.)
1st Company (555 Men, 1000 Veridianitian Horses, Support Staff)
To help with regimental integration Rough Riders were organized into the vaunted first company. 1st Company consists of a Company Command (lead by the skilled Veridianitian Lietenant Hest) and 10 full Rough Rider platoons. Typically used in a reconnassance role (in lieu of Sentinel Squadrons since so many failed to survive the campaign) they can be deployed enmass where the explosive lances, lascarbines, and meltaguns they are typically armed with allows them to deliver a powerful hammer blow.
2nd Company (555 Men, 70 Chimera APCs, 10 Sentinels, Support Staff)
The 2nd Company is the mechanized arm of the regiment. Equiped to a squad with Chimera transports, the Armored Fist squads of the Company's 10 Platoons are used as a reserve force, moving in the reinforce weakened parts of the line or to take advantage of an enemies momentary weakness. The Company typically deploys by Platoon where the squads contain a varied mix of special weapons to support each other. Rarely are 2nd company squads equiped with heavy weapons, prefering to trust in mobility and the power of their mighty, armored steeds.
3rd-6th Company (2700 Men, Support Staff)
3rd through 6th Company form the bulk of the Regiments manpower. Each company consists of a company command unit, 10 full platoons (a command unit and five infantry squads) which are further supplimented by a heavy weapon and special weapon squad. Special weapons are typically determined by mission but meltaguns and flamers are preferred amongst the regiment (this is true in all Companies.)
7th Company (555 Men, Support Staff)
7th Company is the heavy support wing of the Regiment, consisting almost entirely of Heavy Weapon squads, their 'guardian' units, and platoon/company command. All ten company platoons consist of a command unit, 4 five man fire teams, and 5 six man Heavy Weapon squads. 7th Company typically fills two roles: either support of other regiments after contact with the enemy has been attainted or as a garrison, manning and reinforcing strong points and regimental outposts. Heavy Weapons are typically chosen by mission priority, though Heavy Bolters, Lascannons, and Mortars are preferred amongst the regiment (both in 7th and other Companies.) Retreats are almost always to 7th Company held strongpoints and due to this many of the regiment have begun to refer to themselves as 'Guardian Angels.'
50 Ratlings - Ratlings serve as the hunting dogs of the regiment. After the regiment has engaged the enemy, ratlings are dispatched in 5 man kill teams (under the command of a Mister Bagend who holds an unofficial rank of Lietenant.) These teams seek out enemy officers and support to be targeted.
20 Ogryn - The final answer in line breaking, these 20 Ogryn are the final survivors of the regiments recruitment and it is Colonel Pelletier's desire that they should not be wasted. To this end, they are attached to the Regimental Command until it has been determined where they can be of the most use.
General Notes on Tactics
Colonel Pelletier employes a mix arms approach with various elements of the regiment supporting each other. This extends to companies and squads within the regiment as well as the varied weapons employeed by members of platoons and squads. Communication is also key to the regiments success. Helping to keep Colonel Pelletier informed of developments is a cadre of extraordinarily trained vox opperators. These men and women have been hailed as some of the best in a Cadian regiment, their discipline and dedication to their task often showing as they relay information during live fire through the command structure up to the top and often even high, Colonel Pelletier believing that Guard command need be as well informed as he is.
