Vanguard Deployment: This unit can deploy outside the deployment zone.
Hide (forest): This unit can hide in forests until enemy units get too close.
Teef Robbers (Goblin Wolf Chariot) is a Greenskins war machine unit. After riding their enemies down, what grim prize these Goblins claim is their own dark, devilish business.
It wasn't long after they first started using giant wolves as cavalry that Goblin armies began to field wolf-drawn chariots. Cobbled together out of crudely hacked wood or scavenged materials and lashed tight with gutstring cords, all Greenskins hold such rickety constructions in high regard. To be able to rumble across a battlefield mounted atop a chariot is a clear sign of importance. Many tribal Chieftains prefer to ride in chariots, trying to outdo their rivals by fielding the fastest and flashiest contraption.
↑Anti-Infantry: Anti-infantry units have an advantage against targets that are smaller than a horse. This advantage can be a damage bonus against small targets, superior weight used to smash through lighter enemies, or an explosive attack from range that effects a large area.
↑Vanguard Deployment: This unit can deploy in an expanded deployment area, allowing it to start the battle within striking distance of the enemy - or somewhere unexpected.
↑Very Fast: This unit can run circles around most other units, taunting and harrassing the enemy or evading its missile fire.
The intended benefit of this Regiment of Renown is that they have Vanguard Deployment. This is quite niche, as chariots are generally pretty fast and can get onto an enemy's flanks regardless. This does allow them to deploy a bit more sneakily, but chariots are not exactly known for their stealth attacks.
This unit is similar to the Moon-howlers (Goblin Wolf Riders), in that their real benefit is in their increase to Leadership and melee stats. +10 Leadership, +6 Melee attack, and +7 Melee defence are no joke for a Greenskin unit and help make this unit decently sturdy and better at dealing damage. Notably, the missile damage, accuracy, and reload time are also improved upon compared to the standard variant.
