FO's or On Map Guns?

[Bear]

What got me thinking about it was that I was looking through the German Kavalry purchase screen and noticed that there was 3 81mm FO's for the Kavalry Battalion, but the Aufk. Battalion gets 4x 81mm Mortar units. Now I know that the Aufk.'s mortars are in two sections of 2x 81mm mortars each and the Kavalry's are in batterys of 4 tubes each. Now all is fine and dandy if I am playing a QB, as I just take what I can get, but when designing a scenario I have the flexabilty to edit and choose. So historically, I understand the limitations of the Russian command limited their use and often dictated a more direct fire roll. But for the German side this was not so much of an issue. I was wondering more if German and for that matter, British/American ect. tended to use there light artillery at the Battalion level as more of a direct fire asset, or did they opt. for more of an indirect roll as a general tendancy.

The general arty use by U.S., Brit and Gemany was indirect fire at all command levels.
