I would like to suggest the admins to give the choice to the MU commanders to decide what the DO reward will be.
Why would this be interesting?
MU with low level soldiers are more interesting in bazooka's when stronger soldiers are more interesting in Energy Bars.
So in a MU with low level soldiers the reward of achieving a DO could be 2x5 bazooka parts.
For MU with stronger lever soldiers the reward could be 2 EB's.
And in MU's with all levels soldier the reward can stay 1x5 bazooka parts and 1 EB
