Welcome to Librarium Online!
Not really familiar with talos, but they are skimmers right? So don't enemies only hit it on 6's in cc?
The "Skimmer" rule for them is described quite explicitly in the codex and has nothing to do with the Skimmer rules for vehicles (which only vehicles can have). As such, they are treated exactly like any other infantry unit is in close combat.
Why do the survivors remain anonymous -- as if cursed -- while the dead are revered? Why do we cling to what we lose while we ignore what we still hold?
Name none of the fallen, for they stood in our place, and stand there still in each moment of our lives.
--Duiker, "Deadhouse Gates"
