Scenario: I assign a sniper to an enemy with two of the specialist symbols. Do I roll 2 dice or 4? If I only roll 2, how do I get the bonus from the other symbol? Assigning another unit? Also, if I have elite status in that situation, is that 5 or 6 dice?
The key thing to remember is that you assign soldiers to icons not to enemies - you assign the Sniper to a specialist Precision icon, and he is worth 2 dice (3 if Elite). The soldier (if any) you assign to the other icon is worth 1-3 dice too.
