Anyone who has recently seen any footage of helicopters in Ukraine has witnessed what I call “Rocket Tossing”. The helicopter lifts its nose, fires off a ton of rockets indirectly, and then peels away. It has the impression of an improvised, ineffective tactic. But it’s not the former and is arguably not the latter.
It’s important to note that doctrine of the 198X Fuldapocalypse era, both western and eastern, details rocket tossing at length. The huge helicopter losses of Vietnam, the precedent of the Iran Iraq War (where the tactic was used constantly), and that air defense wasn’t exactly getting worse all made for sound reasons to know it. So indirect helicopter fire isn’t that surprising.
So how effective is it? Well, it’s basically a light multiple rocket launcher that can fly. Unguided multiple rocket launchers are area weapons, optimized to cover a large piece of land quickly at the expense of long-term rate of fire. (This is why rockets are considered ideal for chemical warfare). Ideal? Not really. Cost-effective? Probably not. But useless? Nah.
