They target a lot of radar and air defense installations and the like, but they will absolutely choose to go in for an IDF soldier with a drone (where a lot of the undeniable casualties come from). In one of the recent reports on IDF operations, they claimed one dead when it seemed pretty implausible, I always take the denials with an offset and a multiplier. The targets are the military assets. When Israel claims that F-35s being destroyed didn't matter because nobody died in them they are deliberately ignoring this.
