Corrected entry: Abraham picks up a case of RPGs and a launcher from an American soldier. US Soldiers do not use RPGs.
Corrected entry: The herd is deflected to the right, away from Alexandria, so Alexandria is now on the herd's left. When the horn sounds it attracts the herd to Alexandria on the herd's right.
Correction: You think that the wall with the caravan is Alexandria but it is a little set up to make a turn. That one goes right behind Alexandria, then the horn goes off and they find their way to Alexandria.
Corrected entry: In the same episode Glenn falls with Nicholas, we never saw Michonne and the others come back, neither in episodes after. But in season 6 episode 7, when they talk to Morgan, Michonne is there.
Correction: Just because we didn't see it happened, doesn't mean it did not happen. We don't see them go out on all their scavenger runs, or get the supplies for said runs either.
Correction: Incorrect. While uncommon, RPGs are part of the US arsenal.
