well i personally wouldnt use this because you can upgrade leman russ's to have 3 lascannons and they would be able to hunt tanks fine, though they are primarily anti-infantry tanks
personally if i was ever to have a guard army it would be mass infantry or (at the other end of the spectrum) an armoured company w/baneblade.
it would make sense for them to have this upgrade as they are the most diverse type of tank out there. however guard already have tons of anti-tank coices. |
