BattleTech rules rarely follow real life. There are a lot of things that can be done IRL that can't be done in BT. I don't recommend trying to apply real life logic to BT. Even though there are sorely missed things thanks this.
Oh for sure, but in this instance, when a statement is proceeded by "Logic says...", it bears mentioning that there's a real life example of just such a thing, so maybe my question is just a TEENSY bit valid.
In any case, Air-to-Air attacks allow targeting stuff that's tailing you via REAR special ability
"Airborne Units: The same rules apply for fighter units as for ground units. However, a fighter may only use its rear-facing weapons against units that are specifically tailing them (see pp. 58-60), and are within range of its rear weapons. Thus, if a fighter has rear-firing weapons that only delivers damage to the Short range bracket, it may only use these weapons against tailing enemies at Short range."
So I figured it was worth asking if this was possible following these rules, since the Air-to-Air Arrow IV's make no mention of firing arc, only that the target must be medium or closer.
