Some strange behaviour when chasing routers comes from the moment when some men of the routed unit are acutally behind the chasing unit. For example, officers seem to be slower than the rest of their men. The chasing unit "overruns" them without actually killing them (he falls to the ground and gets up again), and then the chasers refuse to catch up with the routers anymore because parts of the routers are ahead of them and parts are behind.
