Sorry Boosted FT wasn't cast on a 16 [my mistake] okay on the shooting. I assume that you want to plant both shots into the middle of DK1.
First shot heads back towards the chaos line 2 inches. I think this should push the centre out from the unit but will still hit 2 DGKs
Roll to Wound 4,5 = 2 wounds
AS 2,3 = 1 saved
Wounds: 1
Hit on the second shot. 1 DGK under the hole and 2 more hit.
6 [under the hole], 2, 4 = 2 wound
AS 3 = 1 saved
wound under the whole = 5 wounds
Wounds = 5
5+1 = 6
2 dead DGKs
leadership test at -1 = 3+3 = 6 passed.
Empire you're up
