Firstly why not come into the modern world & download these games. I never played the originals & from posts other people have placed never will as these games are far superior. Same basic game but a lot of work has gone into polishing the product, & I do mean a lot. Apart from the game improvements that scenerio is still available & a lot more to.
Scouting try to find him nicely & suppresion are what you need. Thats where you miss the vehicles need arty or something else. Same goes for tanks if possible try to attack from nearby cover then you can sneak up, faster you go more chance of being seen but moving one hex beside is completly possible so long as you have stripped it of infantry cover.
I may be wrong here perhaps a designer will chip in but in these games tank crews are normally pretty well trained & will look behind if not buttoned. Against low exp troops I have however in desperation run 3 hexes in the open from the rear up to a unmolested tank unnoticed, incredibly risky mind not a sensible tactic.
