Fire up any number of scenarios. 'Rescue on the Outskirts', for example. Place a Syrian squad on the roof of a bldg, adjoining another identical bldg. Plot a movement from one roof to the other. The squad will exit their current bldg, and climb the stairs of the contiguous one rather than step over the tiny, shin-high wall separating them. Renders urban combat rather farcical, methinks. </font>
