During Col. Ryan's eulogy for Hector Williams (Season 3, Episode 8), he states that Hector was born on November 6, 1976. However, when Mack and Charles visit Hector's grave site in "Hero," the headstone lists Hector's birthday as February 12, 1981.
There are numerous errors on Betsy Blane's Class A uniform in this episode. Most prominently, she is seen wearing both ribbons and medals at the same time. A Soldier may choose to wear either ribbons or medals, but they are not worn together. Additionally, she is wearing Crossed Rifles, the branch insignia of the US Infantry. During the years that the series was on air, women did not serve in Combat Arms roles in the US Military.
