This ability will give every single unit you have on the field a firing and running/speed bonus. This is quite effective in team battles when you are planning a massive flank on your enemies. In 1v1s, it can be used to capture that winning VP forcing your opponent to quit or lose the game. The Blitzkrieg assault also gives a great suppression resistance along with heavy crush on your tanks. Though this is a rather costly ability, it doesn't take away the fact that it is quite useful.
