For Geonosis as the Republic:
I start off as a pilot and grab one of the gunships...I then immediately get people mounted and go take out the two spider tanks. With the spider tanks eliminated, I take a look at the tac-map and see if they're swarming one of my AT-TEs (yet). If not, I go blast the crap out of the tech union ships. Each time a tech union ship is destroyed, you need to double check that they've not taken the derelict CP yet.
Once the ships are down, go capture the spire and roll them up between your forces.
You'll find many of the truths we cling to depend greatly on our point of view -Obi-Wan Kenobi
