Okay, can OKW have a howitzer to because currently it has 1 indirect fire unit. Versus the Mortar HT and Priest.
The infantry support howitzers/field guns are made to be used like the ZiS barrage, fired directly into enemy armies, not used for indirect fire support like mortars.
leig - pack
priest (doc) - stuka (non doc).
MHT? Really? It's like calling Irregulars elite-inf cause they are doc.
And last time I checked, none unit costs 151 fuel ("adjusting" fuel is just shitty argument).
