Red Alert 3 - Allies Mission 9 Leningrad - Hard Difficulty - EASY METHOD!

For a change of pace, I decided to start playing Red Alert 3 campaign missions. My goal is to find a very easy way to beat each of the missions on hard, so that anyone can follow along and beat the campaigns easily. Here's my first instalment, the final Allied mission on hard beaten using a very effective, relatively fast strategy. (Flak trooper spam is almost like a cheat code on this mission!) Enjoy.

Important hotkeys are as follows:
Q: Select all units
A + Rightclick: Attack move. Your selected units will move to the chosen location, but stop and shoot any enemies along the way.
