Objective entities could be randomly placed any time, so a pile of barrels to be taken could randomly appear somewhere or what not. Both teams have to find the location, deploy troops, and then attempt to complete the mission. This creates clash. Defend Friendly One of your teammates is marked for death. Don't let the enemy succeed.
Some object is generated on the battle field.
The team has to find the object and bring it back to base. Different amounts of points would be awarded for completing various missions depending on their complexity. If that team completes this mission they win. The mod could be very configurable. I think this kind of thing really fits into the basic idea really well.
