Refine the best soldiers through continuous training, and show their skills through hard work. As an amphibious elite combat force, the Marine Corps has put forward higher requirements for the physical fitness and skills of officers and men. A brigade of the Marine Corps, known as "the land tiger, the sea dragon, and the air eagle", has been insisting on leading and promoting the war with war for many years, strengthening targeted and confrontational training, and strictly wrestling and training the troops. They not only build a unique military sports training system, but also explore new ideas and seek new breakthroughs in the military sports training mode, stimulate the blood and tiger spirit of the officers and soldiers, and forge the fighting spirit of the officers and soldiers "carrying the water to overcome the difficulties and advancing bravely". Grass and trees sprout, and spring mountains are within sight. In the early morning, a sea in western Guangdong is slowly waking up. The sea is sparkling and the sky is the same. "We can endure hardship in the surging waves, and we can fight on the beach. We can carry the water to fight against the enemy, and it is overwhelming..." A burst of songs came like a wave, breaking the tranquility of a Marine Corps brigade comprehensive training ground. A group of dark-skinned, muscular Marines are coming with high morale. The first lesson of this morning is the ultimate combat physical exercise. The team members should complete 20 training contents within 25 minutes, including crossing the mud, water barrier, lifting logs, crossing fire barrier, climbing high wall, towing crossing, and 400m sea crossing and island climbing obstacles. This training can comprehensively test the basic physical qualities of the players such as running, jumping, climbing, climbing and swimming. When fighting hard, training must be practical. In recent years, the brigade has attached great importance to military physical training around its mission and mission, and has taken it as the cornerstone to boost the generation of combat effectiveness. Taking the opportunity of the tasks such as practical training on the sea, military competition, and joint training of Chinese and foreign joint exercises, they carried out the training of extreme combat physical fitness and amphibious combat skills, highlighting the "sea flavor", "war flavor", and "smoke smell", and comprehensively improving the ability to win in the battlefield in a fast-paced, high-intensity, overloaded, and "Kobila". The sandbag continues to write a new chapter of "Tiger", with the horn and the bow full of strings. "With sandbags tied, you can't be considered as a 'Tiger Company' person. Only after you have experienced the process of hating it, resenting it, and loving it, can you really become a 'Tiger Company heirs'..." At the physical training field, the brigade's "Tiger Company" welcomes 8 new comrades with the traditional ceremony of sandbags tied. Sandbags on your legs? What's the age of this? Some people may ask such questions, and the hearts of the recruits are also full of doubts. "Standing sandbags, cross-country sandbags, swimming sandbags, sleeping sandbags" are the fine traditions that the "Tiger Company" officers and soldiers have been adhering to for 32 years. Xu Gaocai, the fourth company commander of the company, took office in 1992 with sandbags, and asked the officers and soldiers of the company to sew sandbags by themselves using white sheets and other materials, and then fill in fine sand, and bind two 5 kg sandbags each. Under the leadership of Xu Gaocai, the officers and soldiers of the company kept their sandbags close to each other, and increased pressure and hard training of internal skills. The military sports training results were far ahead of the brigade. In that year, the assessment required that the horizontal bar should be four exercises, and everyone in the "Tiger Company" could complete the horizontal bar one to eight exercises; In less than a year, they improved the average score of grenade throwing far course by 6.8 meters to 47.6 meters; Military competition organized in the brigade
