Maybe she can shoot down our helicopter as we fly past the beach and we land behind enemy lines? Or it could be a nameless NPC who does that and she just ends up chasing us down at some point.

What if she's just a regular soldier who shoots us down so after we escape, the blame falls to her. Letting NUA agents escape with knowledge of the empress' defenses would be a hefty crime so that's why she's made a test subject and consequently wants to hunt us down.
