Help me with a basic strategy issue.

You said light tanks, correct? If any of them have high rate of fire cannons (20mm or 37mm), I find that they do a better job against pillboxes than standard HE fire. The burst type cannons seems to have better chances at getting a firing slit penetration than single shot HE rounds.

Assuming you have at least a couple cover locations available, try separating you armor a bit, one or two to a good cover location. Alternate popping up a single AFV at a time with a narrow cover arc centered on the pillbox. Use the shoot and scoot command to limit your exposure time. On successive turns, randomly advance one of the tanks at a time. Hopefully you tank can move up get a shot off (the cover arc will reduce your tracking time, and get back before the pillbox can retarget you. By alternating which tank moves up and fires, you may the gun in the PB spend more time rotating and you don't give the advantage of increased second shot accuracy. Delays can actually let you use multiple tanks in one turn popping in at closer intervals. Ideally you can isolate your exposure for all the tanks to one pillbox at a time to keep your opponent from using cover arcs for his PBs to cover each your hiding places. Smoke can be used if you have it to provide that isolation, if the map does not permit it otherwise.
