Given the fact that you can now just take a formations-based army*, I thought I'd have a try with one if my favourite units from the background.
Comments and criticisms welcome.

Tactics will vary, but broadly speaking infantry kills infantry and vehicles hunt vehicles. Preferably fighting on the defensive unless massively outgunned. The main decision will be whether to deploy the Storm Talons forward or leave them in reserve - they do represent an awful lot of firepower but are extremely vulnerable if they get hit before they can move (if the enemy steals the initiative, for example)
Thoughts?
* In order to be a battle forged army, all units must be part of a legal detachment. There is no requirement for this to be a combined arms or allied detachment.
