Was that way long ago on old pictures. Also during Amerish revamp there were random models placed whi h included vancuards with double machine gun next to main gun.
On a historical note: The PS1 Vanguard was a two-seater. The gunner had access to either the main gun or a coaxial, though he could only use one at a time. The second gun on the PS1 Prowler was manned by a third person - a second gunner. The PS1 Magrider was built more or less the same as the PS2 Magrider in terms of weapon placement and control.
