Another book that explores this (pretty in-depth) is The Forever Peace by Joe Haldeman. It won a couple of awards for sci-fi writing, and I found it enjoyable.

In it there are remote-controlled humanoid killing machines that are piloted by soilders from a bunker through an electronic hole in their head. They can communicate sub-lingually, hear eachother's thoughs, and feel eachothers feelings to such an extent that the men in the platoon (it's 5 men, 5 women) start getting PMS.
