OK, here comes the whole army (at 1500 points). Missing are 10 rough riders on bikes.
First up, the defending infantry base of 30 las/autogunners with commissar, 4 nomads and a warchief.
This infantry base is led by a warlord, a standard bearer and 3 veteran nomads with sniper rifles. They are in the company of an astropath (ratskin shaman)
A firebase of three heavy weapon groups (3 mortars, 3 autocannons and 3 lascannons) are behind cover in the rear.
This infantry troop of 30 las/autogunners is led by a commissar. An outflanking warchief (Al'Rahem equivalent), a ratskin (fluff) and 3 plasma gunners lead the troop.
3 scout seninels with multilasers try to find excellent firing positions and fill in the gap between the outflanking infantry and the firebase.
Another 3 scout sentinels with autocannons and a lascannon try to find a better firing position.
8 basic nomad storm troopers are out on their own, with an agenda of their own.
And finally, 3 missile launchers, 3 nomad juves (no function in 40K, only in Necromunda), 3 grenade launchers, 3 meltagunners, 2 plasmagunners and 2 more storm troopers act as a strategic reserve (meaning they are not part of the 1500 points, but will be used to change tactics in between games)
