Advance Wars 1+2: Mission 5

Grit finally makes his entrance and damn does his voice leave some things to be desired...

So the good news here is that Grit does not have any factories to create new units, so everything he has is all he will get. It is a little important to pick off his infantry north of your start as they can attack your back line or seize infrastructure, plus getting those properties allows you to build bigger, better units.

The main thing to watch out for against Grit is when his power is charged. His indirects are very dangerous normally, but they become utterly broken when he pops his power. I accidentally lose an infantry not realizing I was on the edge of his rocket range, and for most new players, this would be best case scenario.

The good news is that Grit is one of the first COs that get unlocked. So if you want to inflict him upon others, he is going to be joining the ranks quickly.
