Bodyguard Gulag is Grabnatz's bodyguard. Not the brightest of Orcs, he suffers being bullied and pushed around by Grabnatz quite gladly... Gulag must always remain in base-to-base contact with Grabnatz and the two of them count as a single skirmishing unit for the purposes of movement, charging etc, though they can join a unit together.
If they do this, place them both in the front rank. Gulag is immune to Grabnatz noxious emissions - he's used to them!
If Grabnatz is ever attacked in close combat or hit by missile fire roll a D6, on a 4+ Gulag gets himself in the way to protect his master and takes the hit himself.
Note: in both close combat and shooting Gulag may only protect Grabnatz from the first missile or attacks from a single model.
