Arty preferences. What is realistic ?

Hex is 50x50m long... when six 155 shells hits that hex, one of that sheels have very high possibility of being near miss, and effects of that should be similar yo IED. One more thing 155mm has a wide area of effect, you dont really need to hit building/APC/GI to destroy it. 50x50 isn't that much of a space. Ok, i know IED detonating under the tank has much much more effect then near miss, but still we're talkin abut hitting infantry in open terrain. I'm not talkin abut doomsaday arty, deathstar mode. I just think it's weird that HE shell landing between troops dosn't make any damege. I think that kind of explosion shoul at least kill 2 - 3 guys, not to mention high possibility of killing whole squad.
