Team 19 was established on Sunday August 7, 2005 during Seattle's Blood Drive III. The itinerary for Sunday included meeting at a 21 and over establishment, which left several underaged Moped Army members unable to participate. This group, among other over-aged members, decided to depart on a separate moped ride which wound around the city. It was during this ride that the term "Team 19" was born.
Team 19 has continued to gather at rallies over the past year in the spirit of under-aged activities. Team member have even established secret agent names to associate themselves with the group.
A similar ride occurred during Sunday August 1, 2004 during Blood Drive 2 when a handful of members could not enter a club for karaoke.
