Go-cart racing was popular sport for soldiers at the 1st Australian Task Force Base in Vietnam.
The carts are built by the Diggers from salvaged engines and scrap metal, and race meetings are organised
on a dirt track near the perimeter wire as often as operational requirements allow.
In the lead cart is Craftsman Darryl "Jack" Horner, 22, from Brooklyn Park, South Australia.
In the second cart is Corporal Bob Malone, 22, from Red Hill, Victoria.
Both soldiers are from the 106th Field Workshop.
