In fact, SSgt Wuterich fired on the white taxi from a distance (his vehicle is labeled as 4 in the diagram below)....
SSgt Wuterich's view was obstructed by a tractor trailer bed, the height of the white vehicle and a mound of dirt (see aerial photo below, SSgt Wuterich was positioned to the east).
NCIS forensics determined there was a second shooter to the north, which is consistent with SSgt Wuterich's statement that he engaged after another Marine fired first.
In reality, the incident at the white taxi was nothing like the depiction in the film.
