Klever Spanner

Use this Stratagem before the battle. Select one
LOOTAS or BURNA BOYZ unit from your
army that contains 9 or less models for 1 CP, or
10 or more models for 2 CP. Whilst that unit
contains one or more Spanners, you can roll one
additional die and discard one when determining
the number of shots for burnas or deffguns
equipped on models in that unit. This Stratagem
can only be used once per battle
