Will only the wheeled version be selected?
Will only the tracked version be selected?
Or will the K-9 be selected for both?
I have a feeling that if one becomes the K-9, they might allocate the other to another allied nation.
+ Will the M109 Paladin howitzer be phased out? Or will some parts continue to be used?
