Command & Conquer: Red Alert 2 Tips

Dispose of enemy infantry easily
First,play as any soviet country(skirmish Vs.allied)Send an engineer into allied construction yard and take it to ur base(the construction yard repacks and can be taken.You might need a distraction so the enemy doesn't attack it)
1.War factory(allied)
4.Any tank of ur choice
Put the Yuri in IFV,take it in front of their barracks and press Ctrl and attack the ground in front of the barracks.A white cloud will appear which is only anti infantry and will kill infanry without fail.You might need the tank to defend ur IFV which cannot work against tanks an armoury etc.
NOTE:this cloud will kill your infantry also but it will not affect any tank.
