[Mass Combat] What's the point of Raiding the Logistics Force?

[vicky_molokh]

Greetings, all!

Reading the Raid Strategy, I can't see what's the big point: the only reason to prefer Raid seems to be the case when an enemy has a huge Position Bonus (because it gives +1 to the Strategy roll). I don't see the point in attacking the Logistics Force - the effects of failed logistics will not affect the enemy until much later after the battle (a month, right?). Or do the logistics insufficiencies kick in immediately (blown up ammo storage etc.)? I doubt it, but the MC book is silent on the matter.

Thanks in advance!
