But you must remember the hexes are 100 meters from side to side, so even if an infantry squad approaches a tank “from the front” there is a lot of room to maneuver in the hex itself, so your infantry can ostensibly be approaching from the side, around trees and hills, in the FOG OF WAR as bullets are flying and the tank is preoccupied with other things.
Which is the point I was about to make. I’d also like to add to it that though the hex might be a clear, grassy field as far as game mechanics, you gotta keep in mind that the grass is usually very high, has some scrub and trees scattered about, rocks, gullies, maybe even a cottage or two… they’re not flat and empty. So at 100 meters and having some clutter (but not enough to warrant making cover rolls) and such it isn’t unrealistic for infantry to be able to avoid defensive fire from a tank. It’s only when the infantry gets close to the tank (ie: in combat) that the tanks machine guns defend it. Otherwise the infantry isn’t visible to the tank regardless of how many peepholes it has.
