Here is the OBD breakdown, per Club Rules:
4.2 Types of OBD Points. There are three different ways OBD points may be earned by an officer.
4.2.1 Engagement Points. Battle points are earned by playing games. Members may play either side, USA or CSA, regardless of their army affiliation. Points will be awarded when an End Game form is submitted. (Protocol requires the winner of a game submit the End Game form, if possible. If no winner can be determined, the players involved determine who will submit the form. In the event the winner is unable or unwilling to submit the form, it is allowable for the other player to submit the form.)
4.2.2 Administration Points. Administration points are earned by serving in designated command positions within the military groups and/or the Cabinet. The Club President and Cabinet Secretaries are not excluded from serving in some command position within their military group. For example, a Cabinet Secretary who also served as a CC would receive 25 points per month. These points are the maximum that can be earned for a given position, but are discretionary based on satisfactory job performance.
4.2.3 Conduct Points. Conduct points are awarded at the discretion of the CoA, as recommended by junior officers. These points are intended to be used to encourage participation ‘above and beyond the call of duty’, and are in addition to any administrative points awarded.
So the answer to your question would depend on which category we are discussing, although it would probably be safe to assume we are talking Conduct Points. How they are distributed varies from Army to Army, but it's a fair question that should be addressed via the chain of command for you in particular. Some examples o Conduct Awards that I can speak to from the Union side include running websites, writing War College articles, training new recruits, after action reports posted at taverns, tourney participation, scenario design, etc.
