What does the words 'Tommy' and 'hun' stand for?

"Tommy" refers to a British soldier, particularly during World War I, often symbolizing the ordinary soldier. "Hun" is a derogatory term used by the Allies to describe German soldiers during the same period, derived from the historical Huns led by Attila, implying barbarism. Both terms were used in wartime Propaganda to evoke strong national sentiments and to dehumanize the enemy.
