One thing I love about Furina's role in "Reunion" is how that decoy drone tactic is something Western militaries use in real life. The U.N. coalition used it against Iraq during Operation Desert Storm, tricking the Iraqis into firing at the decoys and exposing their anti-air positions. Said positions would then be targeted by strike aircraft using HARMs (High-Speed Anti-Radiation Missiles), which lock onto the radar emissions coming from the AA units. Iraq had arguably the most heavily defended airspace in 1990, and thanks to this tactic (among others) it was utterly smashed.
It's stuff like this that really makes me love the Elemental Warfare series. And having Furina as a fighter pilot was such a treat.
