I doubt that is true. In Iraq and Afghanistan there was wide variation in the number of civilians killed by different units. Some of that may be context-effects, but I doubt all of it. Also, having people in the loop reminds at least someone that this is 'real' and that we need to carry on thinking about it. If you can obliterate enemies' bodies and the only duty on people is to restock the ammo I think that reduces the moral burden of conflict in an unacceptable way.
