Factual error: ACC Pat Gallan wears the ribbon of the Queen Elizabeth II Diamond Jubilee Medal. The medal was issued in 2012. Her medals would be correct for 2017 when the series was made, but not 2007 when it is set.
Episode #1.2 - S1-E2
Factual error: The settlers prepare to burn Verity at the stake as a witch. Witches were never burned in England or her colonies; they were hanged.
Factual error: Every Time the Shadow Raiders deploy to Somalia, they use a Blackhawk nicknamed "Adele" for their missions. I can understand the helos being transported via fixed-wing aircraft, but on their last mission they leave Georgia, and reach Somalia the same day, flying in the Blackhawks. It would take them some 15-20 hours not including fuel stops. Yet the mission is completed in the time it takes to find a bomb in downtown Atlanta.
Factual error: A general court-martial is being held. A general court-martial, the highest level of military court, consists of a trial counsel, defense counsel, a military judge, and a panel that must have at least five officers. An enlisted accused can request a panel composed of at least one-third enlisted personnel. In this TV show episode there were only two officers and five enlisted personnel on the panel. (00:40:50)
Episode #1.5 - S1-E5
Factual error: The senior police officer's name tag reads "Assistant Commissioner" but he wears the rank insignia of a Deputy Assistant Commissioner.
Episode #1.2 - S1-E2
Factual error: The catalogue of errors made by the SAS team (e.g. being caught out in the open, not posting a watch, not using cover) would be unlikely to be made by an ordinary trained infantryman, let alone an elite special forces unit.
Pompeii's Gate to Hell - S4-E8
Factual error: This episode includes a segment about an abandoned dry dock in San Francisco. At one point, one of the commentators several times refers to the U.S.S. Ward as a "battleship," and marvels that it was built in 17 days. The Ward (DD-139) was a 1200-ton destroyer, not a battleship, and was launched after only 17 days, but then took another two months to complete. By way of comparison, the California (BB-44), an actual battleship of 32,000-tons built during the same time period, too nearly five years to complete.
Factual error: The show is set in 1991 yet the Lincoln town car being driven near the start is from 2003 or later.
Factual error: Two women come into town somewhere around San Luis Valley, Colorado with ring-necked Pheasants. The pheasants were brought into US a few times (East coast, CA) but really did not get established until late 1880s and in Colorado likely in the late 1890s (eastern and southwestern). The problem is it supposedly depicts the year 1880. They would more likely may have found some Gunnisons Sage-Grouse nearby or rabbits. (00:16:10)
