The Basij teams are currently patrolling in the capital, Tehran. However, as the report says,
“There have been no recent reports of unrest in the capital that would justify the deployment of ‘strike teams.’”
If these Basij “strike teams” are by chance being placed as advance forces for the Second Signpost itself, then their reason to be in Khuzestan (the area around Susa) would be to make sure the main invasion forces are ushered through smoothly. So, of course the Basij’s presence in Tehran would be unnecessary.
The Persian Ram is to run out (Dan. 8:4) from Susa (Dan. 8:2). I wrote in Daniel Revisited that Basij paramilitary volunteers will likely be the mainstay of Iran’s invasion force (pp 199-200).
Could this be an advance movement for the Second Signpost? Maybe. Maybe not. However, this is the kind of movement we would expect to see prior to the Second Signpost.
