When World War I broke out Father Giuliani enlisted in the Italian Army as Chaplain and fought in the trenches with the Third Army Corps Arditi, the special Unit of the World War I Italian Army; for gallantry in action, he was awarded two bronze medals and a silver medal. After the war, he took part with the "Catholic Legionnaires", in the seizure of Fiume under Gabriele d'Annunzio, the city on the Dalmatian coast, formerly part of the Austro-Hungarian Empire that Italy felt as "Denied" after the victory. After a turbulent period of four years Fiume was eventually annexed to Italy in 1924. He also took part in the Fascist March on Rome.
In 1926 Father Giuliani wrote a book about his experience in World War I entitled "The Arditi". The book was published in Milan by Fratelli Treves Editori and included a brief History of the Third Army Corps Arditi.
In 1936 during the Italian invasion of Ethiopia he enthusiastically enlisted in the Army again, seeing this war against Ethiopia as an opportunity for a new religious crusade against heretics and infidels, and as a tool to export European civilization. Father Giuliani was assigned to the troops under the command of General Diamanti. He fell during the battle of the Warieu Pass (see First Battle of Tembien), while attempting to rescue wounded soldiers. In 1936, as a tribute to his sacrifice he was posthumously awarded the Gold Medal of Military Valor. The citation concludes: "A blow of a scimitar, brandished by a barbarian hand, cut short his terrestrial existence: ending the life of an apostle and beginning that of a martyr."
In 1937 the book, "the Cross and Sword" with his letters and articles written during the Ethiopian campaign was published in Turin.
In 1939 the Italian Royal Navy commissioned a submarine of the Liuzzi class with its name. After the Italian armistice on September 1943 the submarine was seized by the Japanese and given to the Germans, and commissioned into the German Navy as UIT.23. UIT 23 was later sunk by HMS Tally-ho.
