halving firepower - round up or round down?

By 4lterego, in Tide of Iron

couldn't find this in the rules offhand and have a game coming up tonight! Thanks!

You always round up.

Always round up when calculating firepower.

Yep, see for example page 29 Combined Fire - 28 vehicle Damage - page 27 Resolving an attack , there you will find it.
