IT'S JUST NOT THE ROUT WITHOUT BIKES
Opinions may vary of course and I'm only talking about my own collection, but for me the Wolves are an assault force. Cunning, yes. Savage, absolutely, but not undisciplined. Quite the opposite in fact. As I may have mentioned the Wolves were the very first 'army' I ever painted for Warhammer 40,000 and I took them to the 1998 UK Grand Tournament. I wanted to redo the army for years but other than one or two miniatures never quite got around to it, however once I got into the Horus Heresy scene the VIth legion were always on my roadmap. My initial vision for the Wolves was an execution strike force, highly mobile with plenty of outflanking potential. This meant assault transports, speeders but most of all, bikes.
The equivalent of the space marine bike during the Horus Heresy was the Legion Outrider, a Forgeworld kit that uses the plastic scout bike frame, extends the wheelbase slightly and adds extra armour. To fill out the fast attack slot with a proper sized formation took three kits (9 outriders in total) so it wasn't a cheap unit to add, but does completely match the VIth's style. To avoid them all looking like clone troopers I replaced the torsos with ones from different kits including the Wolves legion specific ones, same with the pauldrons. The heads also I swapped out to have a number without helmets, some MkIV and others MkIII or even the heavier Tartaros pattern ones as they really suited the Outriders. Weapons equally were a mix of close combat axes, chainswords or pistols. Again this really suits the wolves warrior aesthetic riding with weapons drawn and helps reinforce the narrative.
