The simple idea of 2 Platoons of
IG with Hit and Run and scout made me shiver the first time i thought in them..... 50 little guys buffed with Hit & Run, Scout, They shall know no fear, posibly hate, and a real chance for Feel no pain .... Scouting forward and jumping a max of 36 `` each turn shooting and charging into combat any unnit in the battlefield.
Korsarrioh Kahn with bike, a
lvl 3 Librarian with bike and BIOMANCY, Techmarine with bike, 2 comand squats with bikes and Grav Guns, 2 Bike squats with Grav guns and combi grav, 1
IG Psiker with biomancy, 1 priest, 2 big
IG platoons with several Infantery squats armed with 6 power axes , 6 melta bombs and 6 Melta guns. That could be the seed of the army. on the second line you could add points with thunderfire cannons or storm talons.
Ive test it and it works, Hit and Run simply enance those platoons into real monster, they can shoot anyplace, anything charge to desintegrate any squat and then go for the next leaving the remains for bikes or for its twin platoon
