[49.19.1] Technically incorrect damage for Grenade Launcher (Automatic) (Non-Inferno Ammo) #5480

I came across this one while trying to figure out the magic behind the Mauser IIC math during my analysis of the infantry weapon abominations added by Shrapnel. This is technically not a bug with MM since both the TechManual and the Infantry Weapon Tables have the same incorrect damage value. I was just curious if this issue could get resolved in MM before any errata since there seems to be a year-old official forum post on the matter that, as of yet, has gone unnoticed.

The Grenade Launcher (Automatic) (Non-Inferno Ammo) when plugged into the conversion formula in the AToW Companion:

AP average for class (B) ordnance = (3 + 5) / 2 = 4 BD average for class (B) ordnance = (10 + 8) /2 = 9 Burst 5 Magazine Size > 3 Weapon is an Explosive/Area or Splash Weapon

So,

Penetration Factor should be 4 / 4 = 1.0. Damage Factor should be 9 * (3.5 + (5 / 5) +1) = 49.5. Reload Factor should be 1.0.

Therefore the final damage equation would be ((1.0 49.5) / 50) 1.0 = 0.99. Not the 1.49 listed.

--The magic of the Mauser IIC math was crazy bayonet nonsense. Where the vibroblade bayonets of infantry guns in TW can apparently detach from their host gun and fly down range up to the full reach of said gun to stab whatever is being shot at. Weird.

It’s our policy to wait until official CGL errata is confirmed.
