So, the group for which I am a Sergeant did let me setup the regiment for them. I tried not to go with anything too much out of the ordinary in order to give them a good understanding of the setting first in a "standard Guardsman's boots". We are Cadian shock, but rolled with Line Infantry instead of Armoured Fist - again, to simplify it.
We got good-quality armour, respirators, microbeads, etc... But most importantly: upgrades for the Lasgun.
But most importantly:
Targeter (+10 on all penalities for aiming), Laser Sight (+10 single shot), Deadeye shot (+10 for called shots), underslug grenade launcher.
My Sarge also got "Get Them" and a high fellowship bonus.
And then... Overload setting.
Which means:
Single head-shots + half-turn aim at +20
Standard attack + half-turn aim at +30
Semi-auto head-shots+ half-turn aim at: +0
Semi-auto + half-turn aim at: +20
1d10+8 + 2 pen (x4 or x3 I dont recall which the ROF is)
Besides putting Kraks in the underslug launcher, which is in our plans - do you have any suggestions on how to maximize and best use our lasguns?
