point man (n.)

"one who leads a military patrol in formation in a jungle, etc.," 1944, said to be from point (n.) in military sense of "small leading party of an advance guard" (1580s) + man (n.). A more literal sense also is possible. Point (n.) in U.S. also meant "position at the front of a herd of cattle," and pointman in this sense is attested by 1903.
