[X] Apologize for the limited use of the proximity fuse option, but point out that it does allow for engagement of aerial targets, especially observing drones. It is also a strict upgrade that did not remove the direct fire ability and the explosive power of the grenades was also improved. If she installs a way to precisely judge the range to small targets, you can change the grenades to time delay fuses.
[X] Suggest to Destroyer that, with her in-built fire control computers and ballistic trajectory calculations, the proximity fuse rounds can give her a safer way to blow up targets from a distance. Safer = less dying. If that doesn't work out, the high-brisbane rounds are still an improvement - we can make production run of those with the old impact fuses.
