LONDON - Great Scot! A shortage of ceremonial kilts could leave thousands of soldiers without a stitch of plaid to wear as they parade to the skirl of the bagpipes. Military officials said Monday that more than 5,000 Scottish soldiers are having to share their kilts because defense chiefs have not finalized a contract to buy enough of the garments to go around.Combat troops wore the traditional Highland garb in battle as late as World War I, but now the plaid kilts are used in ceremonial uniform.
