Last night on the twitter stream for #iranelection, there was a sudden burst of tweets about how tanks were entering Tehran. Others asked for confirmations or photos. None appeared. Then some military folks opined that tanks don’t do well in urban areas and in fact are quite vulnerable. Then others tracked the tank tweets back to their origins. They came from just created Twitter accounts with just a few followers and thus were probable Iran government disinformation and psyops. Thus, within a few minutes, a disinfo campaign was launched, then stopped dead.
