How to make unit slower temporarily? Options

[epicelite]

I am making a single player map, starts out with some titans & an APC going across a bridge, a MCV shows up shortly after and goes across only to have the bridge blown up when the titans reach the other end.

However, the APC gets across well before the titans.

How can I slow the APC down? I tried "fallow friendly..." but it just drives across and goes to the nearest civilian vehicle.

PROBLEM: The bridge is in the air above some water, and the APC drives across and tries to go down into the water to the waypoint.

SOLUTION: ?????
