It came like a thief in the night. I've never seen visibility drop that quickly. It lasted from 2am to abot 6pm. The sky and lanscape was a horrible brownish yellow color. It allowed the enemy to lob mortars and set bombs up from a closer distance to the base. They attacked at noon, fortunately nobody was hurt and nothing got hit. Maximum firepower and zero results. A storm like this hasn't happend since the day I got to Iraq. I will post some pictures of the scene soon.
