From the report, as to the shooters:
[Investigators] determined the two shooters had fired at least 81 shots at police officers. The investigators found an additional 1,879 rounds of .223 ammunition and another 484 rounds of 9-mm ammunition inside the SUV. Some of the rounds were in an ammunition canister while still more were in a black backpack. They also discovered that the assailants had taped ammunition magazines together to make switching them out easier. Inside the SUV, investigators also found what they believed was the trigger apparatus intended to be used to detonate the secondary devices found at the IRC.
The shooters had medical supplies in a blue backpack. These supplies consisted of ibuprofen pills and several quick-clot agents including tourniquets, emergency bandages used for traumatic wounds, and even adult diapers possibly to act as absorbing bandages. They were not wearing body armor. They wore all black clothing, including ski masks, and load-bearing vests. They both wore Airsoft neck guards—used to stop plastic pellets in a military simulation game—which was curious because that equipment would have done nothing to stop bullets.
Their bodies were transferred to the morgue. The male assailant had 25 wounds, most of which were to his legs. He also sustained a gunshot wound to his chin that fragmented into his neck. The female assailant sustained two shots to the head and 13 others to her body.
I would like to see an official report on the shooters, especially the wife. There has been a lot of contradictory reporting on her life in Pakistan and Saudi Arabia and her family ties. When did she get radicalized? Was she an operative? Did she convert her husband or vice-versa? There's been a dearth of reporting on them since December, 2015. All the first responders in the world can't prevent a terror attack by determined perpetrators. Why not expend some effort to understand their motivation and background, beyond the superficial and contradictory news reports? This is about as far as I got on her life in Saudi Arabia and Pakistan.
