Storm Troopers

BS4. 18" Rapid Firing AP3 hot-shot lasguns. 4+ saves.

Airborne assault, you can re-roll scatter dice when deep striking (from Valkyries).

Behind Enemy Lines, Infiltrate and pinning.

Reconnaissance: Scouts and Move Through Cover.

So, the way you use this silly unit is in a all scouting army. They can also go forward by themselves, but it won't be as strong imo.

Meaning, 3xStormtroopers in 3xChimeras, 1xcommand +3/5x Vets in 4/6x Valkyries, with whatever heavy support you want to bring along.

Scout everything forward, and start chopping him out of his vehicles. If he isn't in vehicles, alpha strike his ass to death.

Are you going second? Fine, use your scout move to deploy forward just enough so he can't move without giving you a alpha strike.

Scout those Stormtroopers in their Chimeras! Screw the other abilities, they aren't what you want.

In the all-scout army, you'll probably have a ton of anti-infantry firepower on your Valkyries. They can cripple the biggest threats to your dismounted units, and if everything works properly...the game will be over before it really begins.

They are overpriced, so use them in the overpowered role they seem meant for.

Enjoy. :)
