But... Firepower statistics wouldn't make any sense. In cmx1, either your entire squad was pinned or your entire squad would fire their weapons. CMBN is too dynamic for such a statistic to be meaningful. Sometimes the man carrying your LMG will be pinned, and sometimes he won't. Sometimes he'll have an excellent LOS, or sometimes he just won't be positioned right.
The best thing you can do is know the loadout of the squads, and make decisions based on that. If I'm not mistaken, PzG have an extra LMG - so use they will have a further optimal range. Fusileers have an extra SMG, and so I'll take them in city and ambush style roles.
