Secutarii
Secutarii otherwise known as Titan Guards are badass motherfuckers meant as a military force of the Adeptus Mechanicus' Collegia Titanica.
Developed long ago before even the Imperium existed, these troops were developed in parallel with the Skitarii Legiones of Mars. The Secutarii act as the honour guard and protectors of the Titan Legions. While the role of a Titan is to shatter a fortress or blast enemy formations to ruin, it is the role of the Secutarii to eradicate such threats its survivors might still pose as the Titan presses on towards important targets. The Secutarii devote themselves to hunting down and slaying those who seek to flee from the Machine God's wrath.
Secutarii are split into three distinct groups.
Secutarii Hoplite
Secutarii Hoplites are a type of Skitarii warrior of the Secutarii Titan Guard, equivalent of most anti-armor infantry found throughout the Galaxy. Their role is to mop up survivors left in the wake of the advance of the Titans of the Adeptus Mechanicus with short-range weaponry that nonetheless can devastate enemy armored vehicles.
These warriors typically go into battle with an Arc Lance and Mag-inverter Shield. Akin the arc mauls of the Skitarii Clade officers, and the far larger of the mighty Cerastus Knight-Lancers, the arc lance inflicts damage through short range blasts of coruscating energy that can burn through xeno technology and render mute the machine spirit of even the most heavily armored vehicle. Mag-inverter shields provide the copious power needed by arc lances, and resists blows which would otherwise slay its bearer instantly through utilizing a powerful and sophisticated inversion generator at the shield’s core.
Secutarii Peltast
Secutarii Peltast are a type of Skitarii warrior of the Secutarii Titan Guard, equivalent to most base-line infantry utilized by almost everyone. Their role is the same as the Hoplites which is to mop up any straddlers left after the devastation made by the Titans of the Adeptus Mechanicus. Peltasts are equipped with longer-ranged weaponry meant to counter enemy infantry. They seek targets of flesh and bone that would attempt harm on the great God-Machines of the Legio Titanicus.
These warriors typically go into battle with Galvanic-casters. The Secutarii Peltasts are equipped for all manner of targets. This electro-galvanically driven, multi-function projectile launcher has multiple firing modes that may fire rapid bursts of low velocity, razor-edged metallic flechettes; attack concealed targets with retina-burning ignis charges; fire an armor-piercing inert slug-shot at supersonic velocities; or even fire a barrage of blind canister shot to confuse and disorientate the enemy..
Secutarii Axiarch
Secutarii Axiarchs were a type of battlefield commander used by the Mechanicum's Secutarii guard. These officers displayed perfect dedication and application to the Secutarii's art of war, but also have served on a battlefield where a fallen Titan have been successfully recovered or protected from the enemy. This is the most holy task a Secutarii can perform, and as such the Axiarch's are seen as blessed by the Omnissiah.
Once this criteria has been met, an Axiarch is remade and upgraded into a being that is inhumanely stalwart and nigh-indestructible. They were typically equipped with an Arc Maul, Radium Pistol as well as Refractor Field and Titanshard Armour.
