I have finally assembled my Triaros armored conveyor! Yay! Now my Secutarii Hoplites have a transport! I will also be using it for 40k games. Maybe...
They look great together! I think the Triaros works best as a transport for the Secutarii as opposed to the Thallax, who already have jump packs, or the shambling zombie like Adescularis tech thralls. Those guys don't really need transports, they are basically fodder. If we ever get Skitarii in Horus Heresy, they will probably have access to the Triaros armored conveyor as Dedicated Transport, like the Secutarii. The heavily armored and armed transport seems more like the kind to ferry precious, high-value troops like Skitarii, rather than Adsecularis tech thralls.
It also makes sense for the Secutarii to rely on Triaros armored conveyors to not only allow them to keep up with the Titans they escort, but also to provide resilient protection from whatever foes the Titans may be facing. The twin flare shields they possess envelop them in esoteric fields that repel energy and ballistic weapons alike.
My head canon has it that the Triaros armored conveyor is the Adeptus Mechanicus transport from the Horus Heresy until the present 41st millennium. However, the Skorpius Dunerider was invented presumably by Belisarius Cawl (since, you know, he invented the grav-tanks for the Primaris Space Marines) after the Great Rift, and it rapidly replaced the more cumbersome and slower Triaros armored conveyot because it's more agile, faster, flexible and easier to manufacture. Also costs a lot less resources to construct too. But prior to the Skorpius vehicles, the Triaros was the main mode of transport for the Skitarii.
That's why we don't really see the Skorpius tanks and Duneriders until quite some time after the Fall of Cadia. Though most of the Adeptus Mechanicus have swapped to the more easily manufactured Skorpius Dunerider to transport their troops in the present, there probably exists core maniples who make use of ancient Triaros armored conveyors to ferry their infantry into the thickest of fighting. The relatively few Triaros remaining are under the purview of the highest-ranking archmagi's most valued Skitarii maniples, such as the Secutarii or the first maniples of each forge world. At least that's what I want to believe.
So...please, Games Workshop, provide Legends rules for Mechanicum in 10th edition (or 11th edition) Adeptus Mechanicus!!!! I want to field them in Crusade! Not just the Triaros armored conveyor, but also the Cybernetica automata, Myrmidons, Thallax and more!
