Shoulda brought a deathstrike missile and fought some footslogging marines on the bottom tables, and play next to the khorne lawnmower who tabled his opponent and still lost.
The secret to winning in 40k is to purposely try to deathstrike your own army. Although, Mike Cave was a killjoy and tried to stop the deathsrike before it could fire, but he couldn't stop the unstoppable and his poor 3 marines paid the ultimate price.
