1995 was the original "Command and Conquer" not "Red Alert". In the original C&C the computer wouldn't attack sandbox walls which was basically godmode since you could just fence them off heh.
The computer player would always target your nothern-most structure for airstrikes or nuclear weapons. This persisted to at least Generals Zero Hour (I never played the campaign of C&C3 or 4 so can't comment on them).
