Giants do not attack in the same way as other creatures. They are far too large and fractious to take orders and much too scatterbrained to have any sort of coherent plan. To determine what happens in each Close Combat phase, pick a unit in base contact with the Giant and roll a D6 on one of the following tables. Which table you use depends on the size of the Giant's victim. When fighting characters who are riding monsters, decide whether to attack the rider or mount before rolling on the table.
