For this set up to work you need both. You need to take a focus to activate blaster turret and then Marksmanship to change focus to hits. Otherwise you will have no way to modify your dice. The focus token only allows you to fire the turret not change focus results to hitsMarksmanship seems like a big waste here, as you still need a focus to activate the blaster turret. Creates redundancy. Push and Engine Upgrade can be good on him with the Agromech, but generally BT and the Agro is all you need.Kavil would like a word with you. Also blaster turret is actually pretty good on hwks if you've got rec spec. So basically it's good for hawks and Kavil only pretty much. Kavil being the exception because he gives you 4 dice, take marksmanship and agromech and exp interface and you've got a lot of points but a lot of pain and almost guaranteed hits each turn. Other than that then your better off going for ion turret.Hate to say it, but good riddance. Blaster turret just sucks.Depends on what the twin laser turret does. However then again if it does what I think it does you will never see a blaster turret again.
The agromech is more than enough fir that. Marksmanship is only really worth it if you can make multiple attacks
