I just watched the interview on CNN and the guy that got shot said he and his team were gathering on a block that they believe where the terrorists are. It turns out they were on the wrong side of the block. The terrorists were actually on the neighboring building.
That is why he was standing behind the car to hide himself from the terrorists. But he got hit to realize the terrorist were actually on the other side. So, he got up and hide on the other side of the car. Later, he chased down the terrorist who he believed shot him and he ran into some houses to get information to which way the terrorist went. After the chase, he got the terrorist down and he bandaged him and locked him up.
The reporter asked, "you got shot by this guy, but you still treated him." he said he\'s a medic and its his job to treats them.
