STATISTICS ARE NOT BORING.

Honest.

thought you might be amused by this little calculation that takes account of the ballistic skill, weapon strength and saves in a shooting match between a Space Marine/Chaos Marine and one of the new storm troopers:
Space Marine:

BS - 4 (3+ to hit)
Weapon Strength - 4 (against the Storm Troopers T - 3 is 3+ to wound)
AP - 5
Save - 4+ (for the Storm Trooper)

Therefore:
2/3rds chance of hitting
2/3rds chance of wounding
1/2 chance of a failed save

(2/3)*(2/3)*(1/2) = 4/18 or 2/9ths chance of a kill

Storm Trooper:
BS - 4 (3+ hits)
Weapon Strength - 3 (against Space Marine T - 4 is 5+ to wound)
AP - 3 no save

Therefore:
2/3rds chance of hitting
1/3rd chance of killing

(2/3)*(1/3) = 2/9ths chance of a kill

Statistically, an equal match :) i found that interesting. I hope you enjoyed your last lesson in maths.
