F.O.T.S Line Com-Bat
The abbreviation stands for "Fried on the Side", and therefore the "S" also deserves a period: F.O.T.S.
There might be more F.O.T.S. items with the same typo, this is the one I've just discovered.
Thank you, we'll take care. Should be fixed with the next update (no, I don't have a date for you) :)
