I can only assume this was an intentional decision; after all, the earlier Explorer Scout Manual organized Explorer Scout posts into patrols (called "crews"). (Interestingly, Explorer Scouting also used program committees comprising at least one member from each crew, which would seem to water-down, at least to some degree, the patrol-centric nature of the "classic" system.)
Does anyone have any information about this decision? Do any of your crews use the patrol system?
As an aside, it's not immediately clear to me whether the BSA's decision on this point is in keeping with international practice. While Canadian Venturer Scout companies seem to use ad hoc "expedition teams" rather than patrols, at least some British Explorer Scout units use patrols. WOSM publications, like "Empowering Young Adults: Guidelines for the Rover Scout Section," direct that "[t]he team [patrol] system is a fundamental element of the Scout Method and it exists in every section of the Scout Movement in a way that is adapted and specific to each age group." Does anyone with international Scouting experience mind sharing their observations? Does Venturing adapt the patrol system to our age group, and I'm just not seeing it?
