I loved that game as a kid. I played this for HOURS on end and loved every second of it. Also, micromanaging unit was EXTREMELY effective. Manually controlling a light tank could take out a heavy or even a missle tank pretty easily, due to its speed and speed boost if engaged in combat and manually controlled.
It was hard to the bone - I nearly crashed my monitor playing it out of anger - but today with the possibility of different difficulties - everything stays secure1
I could be wrong but i think the low res of the time probably made it harder too, being probably 640x480 or something. You were pretty zoomed in. I loved this game but it took me ages as a child to work out that it's basically just a race to the flags and you win or lose in the first few seconds of the level.
