With a cat it will mostly be water vapour right? Not really a priority at war but it’s nice. And HICE engines have higher power density, which makes sense for recon drones, unless the tanks nullify that.
Environmental friendliness is way down the list of priorities in war, from the perspective of the army.
Right, that’s what I mean by the article not mentioning any actual advantages, which makes me think they’re not actually winning the tradeoff game.
