There really is no more appropriate word for them then heros. They were former SEALs, not in Benghazi to protect the Ambassador, but when they hear Americans crying for help they decided to do what someone high up in the chain of command (or the Obama Administration) was actively blocking, go render aid. They did not have a weapon to speak of and did not care; they would just pick some up along the way. While they were not in time to save the Ambassador, and eventually were forced to sacrifice their lives, they are credited with saving at least 20 others. As I said, in a word; Heros.
On a slightly darker note, intentionally or otherwise, someone hung theses men out to dry. Support would have reached them in time if any of the calls for help were headed. Those calls were rejected, and it is not unreasonable to say that that decision may be the reason these two heros are not around to tell us their stories themselves.
"A short distance from the American compound, two Americans were sleeping. They were in Libya as independent contractors working an assignment totally unrelated to our embassy. They also happened to be former Navy SEALs. When they heard the noise coming from the attack on our embassy, as you would expect from highly trained warriors, they ran to the fight. Apparently, they had no weapons, but seeing the Libyan guards dropping their guns in their haste in fleeing the scene, Tyrone Woods and Glen Doherty snatched up several of these discarded weapons and prepared to defend the American compound.
Not knowing exactly what was taking place, the two SEALs set up a defensive perimeter. Unfortunately Ambassador Stevens was already gravely injured, and Foreign Service officer, Sean Smith, was dead. However, due to their quick action and suppressive fire, twenty administrative personnel in the embassy were able to escape to safety. Eventually, these two courageous men were overwhelmed by the sheer numbers brought against them, an enemy force numbering between 100 to 200 attackers which came in two waves. But the stunning part of the story is that Tyrone Woods and Glen Doherty killed 60 of the attacking force. Once the compound was overrun, the attackers were incensed to discover that just two men had inflicted so much death and destruction.
As it became apparent to these selfless heroes, they were definitely going to lose their lives unless some reinforcements showed up in a hurry. As we know now, that was not to be. I’m fairly certain they knew they were going to die in this gun fight, but not before they took a whole lot of bad guys with them!"
