"The other two troops in the squadron were ahead of us, so we had to interact with them in that we had to bypass forward of their lines." According to Welch, the forward passage of lines
includes "understanding what their location was, how they were raided and where the points were to get through that without fratricide, injury or damage to any vehicles."
Military police units supported the forward passage of lines
between host nation (HN) forces and divisional units by reducing the congestion in the passage area.
The lesson learned was that adjacent unit coordination is more than sharing tactical graphics, building restricted fire lines, and having an SOP to conduct a forward passage of lines
; this is only a good start.
