Found a nice, pain-in-the-ass-to-reach location to build a base. Noticed my faction was doing literally nothing to stop an NC push. Neither did I; I was holding down the base. Despite this, I have put zero certs into base buildings since it was released.
Eventually came under attack by some skyknight who's first instinct was to abandon his Reaver and shoot rockets at my sole turret. He runs out of ammo. I see a Vanu Liberator attacking a nearby sector, I hold fire hoping it doesn't notice me. Eventually they do, but they apparently run out of ammo. They come back a while later, and somehow blow all their ammo(AT belly gun and Tank Buster) trying to kill my HIVE, but fail. They try to drop their gunner, but the NC pilot from before shows up, kills him, and gets a Tank Buster to the face. Apparently they run completely out of ammo, and try to crash the Liberator into the HIVE. It doesn't work, looked like one guy died on impact, and I killed the other.
I was finally killed by the NC guy somehow hacking the fighter terminal at a nearby base(despite being a heavy) and killing me with lolpods as I was trying to get another turret set up. When I respawned, I noticed the hacked terminal, changed to Infiltrator to unhack it. This got me my 5th daily ribbon, so I figured I didn't care anymore about the HIVE and logged out.
Planetside 2. Yes, I managed to hold off what, based on total server population at the time, was a dedicated multi-faction air attack on my barely-equipped base. Largely by doing crap-all. Actually, I did get the Liberator to waste ammo trying to kill me by shooting ineffectively at it.
EDIT: Loaded up an old save that I had little idea of what was going on, except that it was a Tau campaign. Turns out, it was a mid-battle save while I was on the receiving end of an ass-kicking at that hands(feet?) of the Eldar. My troops were getting cut apart left and right by Howling Banshees, all scattered to hell, and most of my strategic points were under attack as well. Shas'o Kais was almost dead.
I pulled everyone I could back to base and started building more Fire Caste and Pathfinder squads. Few enough of the Eldar followed allowing me to regroup and destroy them. One of the Fire Caste guys even managed a melee synch-kill on of the Banshees - which involved him bashing the Eldar in the groin with his rifle, then shooting her in the face repeatedly. Not to be outdone, Shas'o Kais pulled off a synch kill on a
Harlequin, punching her in the face, then shooting fusion blaster rounds through her face.
After that, it was just finding the two enemy bases and melting every Eldar from over a screenlength away.
