"When resolving air-to-ground combat rules (see pp. 55-58, AS) the pilot with this SPA can execute either “double strafe”, or a “double strike” attack in a single ground-attack pass. The double strafe attack allows the unit to break its normal 10-inch strafing run into two strafing areas, each at least 2 inches long (and 2 inches wide), with a total combined strafe line of 10 inches.
The double strike attack, meanwhile, allows the unit to deliver two strike attacks in a single pass over the battlefield.To"... The double strike attack, meanwhile, allows the unit to select up to two units for half damage (even with ENE) in a single pass over the battlefield."
