Human soldiers are exceptionally expensive. You can see that in both traditional foot-soldiers and in other areas like ships and planes, where the costs skyrocket because of needing to design around / for the safety of people first.
Robot soldiers will be far less expensive than human soldiers in every respect 50 years from now. A robot soldier can be powered down, and stop consuming resources when not needed (which is most of the time).
If you could produce a robot soldier that did what humans do, with a 5 year shelf life, and you could sell it for $400k to $500k, they'd sell like crazy. Just match the 5 year cost of a human soldier, then by removing the human soldier casualty angle it becomes well worth it to a government.
