[Wonder]

In my experience the most useful form of fire support is 155mm artillery that also has cluster munitions. I once was playing as Swedish defenders against a Russian advance. I saw a delicious bottleneck in form of a bridge, so I mined my end of it and had infantry to make sure nothing got through.

The infantry units came under heavy fire from the T80s and T72s parked on the bridge a couple of hexes away from them, so I called an artillery strike using CM on them. I usually use my FO to direct artillery for faster delivery even if they don't have LOS, but this time I knew accuracy would count more. Besides, my friendly infantry that was under fire was too close, so I used it to direct fire instead.

The result was devastating! The first single hit took out 4 T80s and 1 T72 parked in the same hex in addition to 2 more T72s parked in adjacent hexes! The remaining rounds didn't have much else other than their crews to take out!

Then again of course, the conditions were ideal; My spotter had LOS on the target, and the tanks were stationary and bunched up in a single hex on the bridge with no cover available.
