Varuna is a PanOceania sectorial which, despite its title as an "Immediate Reaction Division", excels at defence. With Fireteams which allow easy mixing of units, Varuna has excellent firepower at a relatively low price. Varuna has weaknesses, primarily quite limited options for offensive troops to move into the enemy's half of the table, but has enough tricks to play around them and enough raw firepower to dictate the flow of the game.
