Abstract: Xi Jinping’s thought of strengthening the army in the new era is infiltrated with the spirit of revolutionary heroism. At the same time, it also highlights the revolutionary heroism of the Supreme Commander of the Chinese People’s Liberation Army, namely, the heroic spirit and boldness of daring to fight and daring to win; the temperament of the commander in chief in being good at planning, having the courage to make decisions, and grasping the modern warfare and military laws; the leader’s demeanor of going deep into the troops, caring for the soldiers, and winning the heartfelt support of the officers and soldiers; and the revolutionary heroic responsibility of “no trouble and no fear”. Today we should inherit the spirit of revolutionary heroism, learn from and implement Xi Jinping’s thought of strengthening the army in the new era, which is of great practical significance to maintain the purpose of the People’s Army and achieve the goal of making powerful armed forces. That is also an important link in improving the national spirit.
