"The first upgraded Vedettes rolled out from the Hellespont plant in October 3054. The design saw its first field action nearly a year later with Christobal's Regiment, part of McCarron's Armored Cavalry. The Regiment had been stationed on Harloc when the planet came under raiding attacks by the Arcadians, a mercenary unit under contract to the St. Ives Compact. For the better part of a week the Regiment pursued the Arcadians without success. Then the Arcadian commander, apparently unfamiliar with the planet's terrain, led his force high into the Owen Stanley Mountains, unaware that the area was accessible by only one pass. In response, the Regiment commander set an ambush by ordering his Vedettes to dig in along the sides of the pass. When the Arcadians attempted to exit the area, the Regiment 'Mechs forced them through the pass, where the Vedettes engaged them. Seven Vedettes and their crews were destroyed in the fighting, but not before they destroyed an equal number of enemy 'Mechs."
