Having just tried my hand at some reserve duty...this was a major Thargoid confrontation. Holy moly, that was some furball! Dozens of Targoids, probably hundreds of robot fighters, laser trails and molten hull plumes everywhere...framerate plunged....what a bonanza! It was quite intense sitting there with the fleet watching the cloud of shiny dots approaching closer and closer. Kind of like a Minas Tirith soldier must have felt

. Very fun. But it seems the estimate of the naval reserve officer was a bit low (when he said 80% of the reservists do not return from duty). My fellow reservists and naval pilots do not seem to grok the fine art of Thargoid destruction and taking out a Thargoid invader all at once rather than just poking at them and making them mad, which of course makes things much worse.
Are such battles survive-able (by some means other than simply running away or just avoiding the service altogether?) Should one stay back off the front line? Outflank and take up the rear? I'll experiment...
One another note, how do you know when the duty is finished? I had a much smaller Naval/Thargoid encounter (which was also very intense ... both shields down, robots in hot pursuit, death imminent...and all of a sudden they all turned white...what a relief!) where all the Thargoids were destroyed, and then fellow reservists and I mopped up the robot fighters, then the reservists and the navy jumped out of the system. But the game didn't indicate that the service was complete, does one have to return to Seccom to finalize a reserve run?
