Finally got me the Alreham (or however its spelled and no demonllama didnt finally send it, I bought it at a local shop) model and I was wondering why they have him listed in the GW site in the hq section but not chenkov. They have his model listed in the collecters section and not even listed as being him.
Why do you think this is?
Has anyone ever used him? how did he do? How do conscripts do?
For that matter, has anyone ever used al reham? How did he do?
