The FanPro Commandos were freelancer or volunteer BattleTech playtesters, demo agents and promoters for FanPro. The group as such was set up by FanPro shortly after they had acquired the full license for what was then "Classic BattleTech".
In the post-FanPro era, after Catalyst Game Labs took over the BattleTech license, the concept of the FanPro Commandos carried on as the "Catalyst Agents".
A webzine called Commando Quarterly was published that featured largely in-character content in a similar fashion to the BattleTechnology magazine of old, including "Worldbook" articles, in-character ads and communication bulletins, short stories and fiction, essays, and scenarios. Later issues also included Shadowrun content.
The magazine was available for free download via the (now defunct) FanPro Commando website.
The FanPro Commandos notably hosted a number of worldwide events where fans could partake in scenarios and, through gameplay, determine the canonical outcome of the situation within the BattleTech universe.
The Battle of Monte Diablo
The Battle of Monte Diablo was run on 2 March 2002 as the inaugural FanPro Commando Worldwide Event. It focuses on a non-pivotal battle during the FedCom Civil War, because FanPro did not want to have an unexpected scenario outcome affect the predetermined storyline.
Trial of Retribution
Trial of Retribution was originally scheduled to be run on 1 February 2003, the day that the Space Shuttle Columbia disintegrated. The scenario features a space battle, and Scott "Clutch" Taylor postponed it because he did not want the Commandos to be running games featuring exploding spaceships just hours after the Columbia desaster. The event was rescheduled for 8 February 2003.
Lawyers, Guns, & Money
Lawyers, Guns, & Money was run on May 24, 2003.
Kings & Pawns
Kings & Pawns was run on November 20, 2004.
Operation Higashikuni was run at GenCon in 2007. It unexpectedly ended with a Word of Blake victory, crushing Chandrasekhar Kurita's forces at the Ruins of Gabriel in their first battle after having been given a slew of sourcebook fiction and BattleCorps stories building them up as an elite anti-Blakist strike force.
