There are a half dozen references to the "6th Benjamin" dotted throughout Jihad Hot Spots: Terra, and I'd assumed that they referred to the 6th Benjamin Regulars. However, the only place where more the name is given is in a news report summarizing the events on the Lyran front of Operation SCOUR in 3077 on pages 65 and 66.
On page 66 it states that "Sadly the same was not true for Wing just two months later. The Third Free World Guards were ready and savaged the Sixth Benjamin Guards".
I can't find any other references anywhere to a Benjamin Guards formation - is it perhaps a typo for the 6th Benjamin Regulars? I'm wondering if perhaps Myra Kellison made a slip of the tongue when giving her report.
