5.1.51 - 0245 Finally saw my first Goliath. Makes a Stalker look like a field mouse. The massive guns and armor look like something off a science fiction mag. Without tanks or other heavy weapons, open attack is suicide. Since each Goliath carries multiple spires we had to use hit-and-run tactics to best it. Attacked with small squad and lured it away from the main force. We weren't a big enough target for it to launch spires, but we kept swooping in and attacking so it couldn't ignore us. Took nearly two hours but we finally brought it down.
