Advance Wars 1+2 Re-Boot Camp: Battle Mystery (Sami) 4/300 [AW1 Challenge Campaign LTC]

In this mission, you are supposed to hide your inf and survive for 8 days. However, just like in the original AW1 game, your "endangered" inf is able to clear the map within 4 days. This is the Lowest Turn Count (LTC) with a perfect score of 300 points. Sadly enough, there's no special dialogue for such a performance. It relies on an exploit, the rocket doesn't fire on the HQ inf. I think it's because when you surround it with your units, it triggers a "withdraw mode" implemented by WayForward to prevent chokepoints. I replicated the strat 3 times in a row and it seems 100% consistent, but let me know if you have trouble with it, or if you can get the rocket misfire with different moves.
