抗战时期，新四军在敌后义无反顾地坚持长期抗战，给日伪等反动势力以沉重打击的同时，自身也有极大的伤亡，因此能否持续稳定地获取后勤物资、保障官兵的生命安全就显得极为关键。受自然环境及残酷的战争影响，新四军后勤保障工作的开展异常艰巨。新四军立足于战局，灵活机动地采取包括取之于敌、取之于己、取之于友等方式，从生活、军械和医疗三个方面来满足全军官兵的军需补给需要，有力地保障了全军官兵的生存和作战行动，为部队的发展壮大和抗日战争的完全胜利提供了坚实的保障。总结其经验启示，对于开创新时代强军强国新局面具有重要借鉴意义。

During the War of Resistance against Japan, the New Fourth Army resolutely persisted in long-term resistance behind enemy lines, delivering heavy blows to reactionary forces such as the Japanese puppet regime, while also suffering significant casualties. Consequently, the ability to continuously and stably obtain logistics supplies and ensure the safety of officers and soldiers became critically important. The natural environment and the brutal war made the logistics support work of the New Fourth Army exceptionally challenging. Adapting to the war situation, the New Fourth Army employed flexible strategies, including sourcing from the enemy, self-sufficiency, and assistance from allies, to fulfill the troops’ needs in living necessities, ordnance, and medical care. These efforts effectively ensured the survival and combat capabilities of the troops, providing a solid foundation for the growth and success of the New Fourth Army and the ultimate victory in the War of Resistance against Japan. Summarizing these experiences offers valuable insights for advancing military and national strength in the new era.
