From Defense Media Network:

On Dec. 10, 2013, Master Sgt. Ivan M. Ruiz, a Pararescueman, was attached as the lone rescue specialist to an Army Special Forces team assaulting a Taliban stronghold. The team inserted into the Mushan village area in no-visibility conditions due to the CH-47 Chinooks creating a dust and sand cloud at the insertion point. Despite this, Ruiz quickly gathered his element of Afghan commandos and moved rapidly to the objective. While they moved, an orbiting flight of AH-64 Apache helicopters observed armed insurgents maneuvering into attack positions, and began engaging with 30 mm cannon fire.
