Working on making a Mordain army (it's all on paper right now) and I have a question on stacking leadership for Modrian's.
I found an older thread about it not working with Commissars

But my question is about a Commissar Tank (Officio Prefectus Command Tank). For 2CP you get "Use this Stratagem at the start of your first battle round, before the turn begins. Select one Leman Russ from your army. All friendly
AM units have a leadership characteristic of 9 whilst they are within 6" of this vehicle"
1) I want to confirm that it reads that this is for the duration of the battle as there is no end (ie" end of turn" like the Mobile Command Vehicle for chimera)
2) does this stack with Mordians +1 leadership Parade Drill (and +1 leadership Regimental Standard)? Can I effectively make Leadership 10/11 guardsmen?
