Flat approach lane in and out of Naga territory, rising into hills on the enemy side of the trenches.
The entrance corridor in and out of Naga Territory is relatively flat, but it gives way to a few small hills on the Naga side, just south of the enemy's own trenches. Those hills are where Tran marks the Artillery Batteries on the map.
As the only route in, the corridor defines the shape of the whole southern assault: the 106th Bloody Leeches must cross flat ground, break the Enemy Trench System, and take the high ground beyond it, all while the mobile trebuchets keep firing.
A flat neck of ground between territories, opening onto low hills beyond the enemy trench line.
The only approach route for the southern assault into Naga territory.
