I agree with that. Something as simple as changing parts on some vehicles when a guy can hold it up to the right location with one hand and screw it back into place with the other, a female has to have an elevated jack OR a guy to hold it.
What difference does that make? A valuable jack is put in use for a lightweight job or 2 troops are required to do a one person job.
A million different things, from digging a foxhole, quickly setting up a defensive position in a bombed out building with heavy timber and stones, opening a jar.
