When Williams was with the jungle tribe he had a Cross tattoo on his left pectoral muscle, however when the medical examiner is prepping his body to retrieve the bullet there is no tattoo.
The medical examiner, describing the bullet that killed Hector, says that it "looks like it came through the neck here, snapping the cerebral cortex . . . ." The phrase "snapping the cerebral cortex" doesn't make any sense. From the X-ray, the bullet appears to have passed through the fifth cervical vertebra (C5). Injuries to C5 are not necessarily fatal, but in this case the bullet caused extensive secondary damage.
When shown in Class A uniforms at the funeral, Jonas has a Special Forces unit patch on his right shoulder, with a Special Forces Tab above it. The Special Forces Tab is worn on the right shoulder only (same with Ranger, Sapper, and President's 100 tabs). An Airborne Tab is actually part of the Special Forces unit patch (like the 82nd and 101st Airborne), and should be worn on the right shoulder above the arrowhead-shaped patch.
When loading Hector's remains into the hearse, the flag draped coffin is loaded in backward. The field of stars is at the head of the coffin and loaded into the hearse first.
At the Funeral, COL Ryan states Hectors DOB is Nov 16, 1976. His headstone reads his DOB is Feb 12, 1981.
