I don't like wars, but being able to build a wall out of some broken concrete blocks without it being man handled is a good feature I believe.
Also being able to build during a long period of time (during the night for example) make the job less exhausting.
Also one could think of it as an assistant: put some augmented reality display, and let the machine showing to the operator where to put the rock.
Or help for building records: you keep the operator part, but you record the scans and position and weights during construction phase, so you can eventually run simulation later to know how the wall will change over time etc.
