Kenneth and Bella Yan formed Yan Manufacturing in 3009 after Kenneth retired from over forty years of active service as a firefighter with the New Samarkand Fire Department. The Yans loved to fly and owned two older-model Wakazashi Airframe’s Ruckus-class acrobatic helicopters that had been handed down from Bella’s side of the family. Using a sizeable amount of their savings, the Yans entered the very niche market of do-it-yourself chopper kits. The small company sold three their first year and the company never seemed to be destined for anything but a hobby for the couple until 3013. During the Galedon Acrobatic Tour, Michael Hulis managed to score a 97.23 (out of 100) using a Yan Stutter-class single-seat chopper, catapulting the small company into the spotlight.
         Demand outstripped supply in a matter of months and the Yans began expanding their business. When Kenneth died in 3017, Bella sold the majority shares to Luthien Armor Works with the stipulation that LAW retain the company’s name and focus of producing small, compact VTOL airframes. LAW happily complied and immediately began designing and producing VTOLs for the open market.
         Buoyed by the instant success of their VTOL, LAW began testing other airframes for possible construction. Though several dozen designs ended up as scrap on the drawing room floor-thanks to cutbacks in most non-BattleMech departments-the engineering team did hit upon a design model that could be used by police and ISF forces alike with little adjustment. The massive "Peacekeeper" worked well for the police and ISF until the Jihad when they proved too large and slow to survive. After the Jihad, Yan began building a smaller Peacekeeper VTOL to replace the dead pre-Jihad model.

         Built for more mission-specific roles centering on local Special Weapons and Tactics (SWAT) teams, massive the Peacekeeper can quickly get these specialists into position for time-critical insertions. The Peacekeeper is built around the infantry compartment, which is roomy enough for a jump-equipped platoon of troopers.
         Although sporting a Shigunga SRM-6 rack and twin Rorynex mini-guns, the Peacekeeper is rarely in a position to use deadly force. In fact, most police-equipped Peacekeepers are loaded with rubber bullets and special tear gas missile warheads for riot duty. Some city governments cannot afford to maintain the costly fusion engine and so they replace them with an ICE. These replace the missiles with a two-pack system.
         Peacekeeper VTOLs are also prized by some ISF DEST teams as well. Loaded with live ammunition and heavily armored, these Peacekeepers can maintain enough of a defensive posture to provide air cover for their insertion team. The inherently quiet fusion engine and active vibration control in the main rotors keeps the VTOL quiet even in a rural environment, allowing the DEST squad a good degree of anonymity.

         Designed and built after the Jihad, the new Peacekeeper is used only in the modern Draconis Combine. ISF special forces use its whisper rotors to perform quiet infiltrations, while city police forces use it for its intended purpose of carrying a SWAT.
