Advance Wars 1 Advance Campaign - Mission 2 S-rank

Mission 2 complete! This was much harder than I first anticipated.
Turn Limit: 13 days
Difficulty: 7/10
Luck Factor: 2.5/5 (1 being little luck required, 2.5 being some required, 5 being very luck-based)
Key Notes for S-ranking:
1. You have to route all units. I have tried capturing the HQ within 13 days, and its near impossible. There are too many obstacles. So focus on killing everything.
2. A small mech spam is required to clear the units directly above your base. Eventually, the artillery and tanks will move down close enough and you can swarm them with a small squad of mechs. Don't overdo it though. You need an ample amount of tanks for the frontline.
3. Abuse the AI's idiocy one again. They tend to love rocketing and artillery-ing your tanks and infantry over your Mid Tanks.
4. Keep your Mid tank healthy and supplied. You only really have time to build 1 Mid Tank, so keep it strong!
5. Keep an eye on his CO Power gauge. Use scapegoats or dodge when you can.

I know this is an old video but could you maybe turn off the animations instead of speeding it up? It ends up being very annoying.

1:28 enemy infantry above river doesn't move. Impossible to replicate. I swear I've spent over 10 years trying to get S-Rank on this damn level.
