strafing a stygian armor force

Grenada Reconquest- Iberian Campaign- Iberia- A Stormtalon from the Apocalypse Angels chapter strafes a stygian force on Iberia.  With the Imperial forces maintaining almost complete control of the air they were able to successfully engage and devastate Stygian troop movements eliminating mobility from the Stygian defense and ensuring that reserves could not be brought up to plug holes the Imperials cut through Stygian lines.
