Polizon was a gimmick taken for some time by the wrestler later known as Pierroth II while Xibalba had worked for IWRG under that name for many years before becoming part of the group. The third version of Los Oficiales was the least active as the three rarely teamed in the year or so it existed and never won any championships. In 2006 Cyborg reformed Los Oficiales once again with himself, Magnum Project and AK-47. AK-47 had formerly worked as Bombero Infernal and only wrestled as AK-47 for a matter of months before moving on to a new character called "Kraneo" ("Skull"). Oficiales V4 never won a title, although Cyborg and AK-47 (billed as Kranero) teamed up with Xibalba to win the IWRG Intercontinental Trios Championship – while they were never billed as "Los Oficiales" the team was a mix of V3 and V4. In the spring of 2007 IWRG officials decided to form a new version of Los Oficiales, selecting three IWRG regulars to be repackaged as the masked Oficial 911, Oficial AK-47 and Oficial Fierro. The team was unveiled at a Lucha Libre festival in May, 2007 and immediately began working in the Trios division. On July 7, 2007 the trio defeated the Japanese trio of Kai, Sasaki and Yamato to win the Distrito Federal Trios Championship, a title that had been relatively inactive up for at least a year before Los Oficiales won the belts. Often IWRG introduces a new "concept" Trio that fades away after a few months, but this version Los Oficiales sustained their success by repeatedly defending the Trios title against such teams as the "tecnico" team of Freelance, Kid Tiger and Star Boy, former Oficiales Capitan Muerte, Cyborg and Xibalba and "rudos" Los Payasos (Coco Verde, Cocochips, Cocolores), successfully taking on all comers, regardless of them being "tecnicos" or "rudos". Los Oficiales would go on to defend the Trios title nine times all together, giving credibility to both the Trios championship and to Los Oficiales as a group. On September 28, 2008 Los Oficiales became double champions as they defeated Cyborg, Kraneo, Xibalva (who had all been members of previous incarnations of Los Oficiales under various names) to win the IWRG Intercontinental Trios Championship.
