If you aren't seeing teamwork, you aren't in my squad. A few of you can probably attest to the how much of a Commissar I act in regards to making sure my squad (aptly named Teamwork), follows my orders as close as possible.

I've had many GREAT experiences with those who actually work with me (Lance and someone else I know around here), and I can't count them all.  I've had them in space and on the ground. Whether in a tie fighter or marching across Espa to get to Jabba's.

I think my most memorable was a battle in Endor where after fierce fighting, my squad of stormies and I had been pushed back to the fork of Outpost and Speed Wreck. Ordering my squad up into the outpost, we were rather bored as all six of us stood around, one of our speeders running a patrol as our AT-ST sort of wandered around.
A few stragglers came by, but the AT-ST took quick work of them.
After awhile, however, the speeder wreck had been taken and we found ourselves at the front of a massive wave of Rebels headed our way. As they pushed against our south exit, I ordered the AT-ST to give a hand and told the trooper on the bike to get off and help us.
The battle quickly turned into a fight on the walls as we tried to keep the rebels from pushing around us. When they started entering from the West, I had our AT-ST move in that direction to help out the non-squad stormies that had taken up guard there. Several times the non-squadies by the east entrance would be pushed back, and my squad on the wall would turn our guards towards it in order to keep them back before looking back to the South exit.
They began to swarm over the walls and the stormies were being pushed back further. I ordered my squad off the wall and we made a mad dash back towards the capture point as the AT-ST was finally taken down. Of course, a squad doesn't last long against grenades in that small point. But it really felt very siege like.

The battle ended with a well tried defensive around the bunker, but unfortunetely, we lost the game.
