Advance Wars 1+2: BHR Mission 21

We hit the mission that endears Kanbei to many of the fanbase. With his people in danger, Kanbei dashes through Adder's trap to save them. You need to time your movements through the lasers and chokepoints to get through without taking too much damage (destroying the lasers is an option). As long as you can break the bottlenecks before the infantry all get to the cities, you can remove the time limit and deal with him at your comfort (if you don't mind losing speed score).
