Danger International
I was flipping through Danger International last night, and I thought I would post its rules for high explosive rounds. They are NASTY.
First the rules, from page 59: "Roll the explosion damage listed, and apply it to any target in the same hex.For each hex away from the target hex, remove the largest die: the target takes the remainder. For the SHRAPNEL (emphasis mine), roll an attack roll using the OCV listed. All targets are DCV 0, unless they are Prone, in which case they're DCV 4. The shrapnel damage works like Autofire;for each 2 points the roll is made by, the target takes that much damage.
The yhave info on grenade rounds for launchers, hand grenades, mines, mortars, and HE shells. I'll post the entire chart if ther is interest, but here are the stats on a 500 lb. bomb.
500 LB Bomb 26d6x OCV 15 R MOD -1/2" Shrapnel 2d6
So using average effect, a taget in the targeted hex would take an initial hit of 91 stun and 13 body, then assuming a to hot roll of 11, against a dcv of 0, the taget would take 8 seperate 7 body/21 stun hits. I think thats going to do some damage to a station wagon.
