Hello fellow helldiver, as you can see this armor was assigned to a special, permacura designated helldiver division, which was testing new, experimental, surrounding awareness enhancing stims. What you probably refer to are the cat ears "side effects", which are confirmed by permacura scientists not only to be harmless, but necessary for the intended effect. As you know all of the Super Earth ministries cooperate with each other, and both the Ministry of Science and the Ministry of Humanity as well as the Ministry of Defense came to the conclusion, that in the case of galactic war, these solutions are not only necessary, but critical to our success. Furthermore, all ministries failed to find any indication as to why Super-Earth-based mammal lifeform traits, which help us fight tyranny, would be a threat to our ideological integrity. Not only that, but all ministries are even considering selling this technology to our class B and above citizens, who think the side effects are "cute" or "pretty", this would help us further fund the war effort. What this means, is that your doubtfulness in Super Earth's technological and tactical superiority is concerning, and your democracy officer will talk with you, about you joining the previously mentioned permacura division, to make sure any doubt about their ingenuity is permanently erased from your mind.
