What are good strategies for the game Red Alert?

In Command and Conquer: Red Alert (1996) so-called tank rushes were a dominant strategy for players using the Soviet forces. One extension of this for the Soviet forces in Red Alert 2 was a Flak Cap (Flak Capture) Rush. The Soviet player would quickly load two engineers (units capable of capturing enemy buildings) and a Terror Drone (a unit that rendered vehicles useless so early in the game) into a Flak Track (a transport) and rushed the enemy base. The idea was that either the engineers would capture the enemy Construction Yard - their most vital building - or the Construction Yard would turn into a vehicle in which case the Terror Drone would hop in. Either way, the enemy loses their vital means of production is effectively doomed from that point on, unable to advance any further. Another method for Soviets is to continuously produce Conscripts. This method is to swarm the enemy using numbers since Conscripts only cost $100, and therefore are inexpensive and expendable.
