Enhancing a soldier’s capacity to fight is nothing new. Arguably one of the first forms of enhancement was through improving diet. The phrase “an army marches on its stomach” goes back at least to Napoleon, and speaks to the belief that being well fed enhances the soldier’s chances of winning a battle.
But recent research has gone well beyond diet to enhance the capabilities of soldiers, like purposefully altering the structure and function of a soldier’s digestive system to enable them to digest cellulose, meaning that they can use grass as a food.
Perhaps their cognitive capabilities could be substantially altered so they can make more rapid decisions during conflict. Or their sensitivity to pain could be diminished, or even the severity and likelihood of post traumatic stress disorder (PTSD) reduced. Or even the direct wiring of prostheses to their brain.
This kind of biological and technological enhancement is often referred to as developing “supersoldiers”. It’s not science-fiction; research is underway around the world. And it brings with it a host of ethical concerns.
One concern revolves around the capacity for a soldier – or any other member of a military force – to give meaningful informed consent to partake in clinical research or undergo enhancement.
The concern here is twofold. First, some of these interventions would be confidential; a military might justifiably want to keep new technologies top secret. This need for secrecy can impact how much information the subjects of enhancement receive, thus impacting the “informed” part of informed consent.
Second, we might have concerns about whether a soldier can actively consent to enhancement. That is, the hierarchical command structures and training in the military may impact the soldier’s capacity to refuse enhancement. Given the prominence of informed consent to medical ethics, this is a core issue for enhancement before we even get to conflict.
Numerous forms of enhancement look at ways of indirectly or directly impacting the soldier’s cognitive capacities. One example is countering the need for sleep through the use of drugs like amphetamines or Modafinil, or other longer-lasting neurological interventions. Another is enhancing a soldier’s capacity to make moral decisions.
