On September 10, 2043, the morning after the rain was particularly sunny and the air was exceptionally fresh. At half past eight, the freshmen came to the playground on time for training. When our 4301 class signed up as a team, everyone was surprised to find that Tian Xiaorui was already in the training queue. Instructor Kan stood in the center of the queue, and Instructor Yan stood next to him. Instructor Kan said: "After two days of queue training, everyone has made great progress, and from today we will carry out obstacle crossing training." Instructor Kan deliberately paused and said, "What is obstacle training, who can tell me." ”

In fact, Instructor Kan didn't really want anyone to answer, Instructor Kan was playing tricks to arouse the interest of the students.

Instructor Kan said: "The so-called obstacle crossing training includes several basic training subjects. First, it includes crawling forward. Second, it includes crossing a single-plank bridge. Third, it includes climbing over a two-meter wall. Fourth, it includes climbing over a three-meter wall without any tools. Fifth, including high-altitude bridges. Among these subjects, there are both individual soldier training subjects and group training subjects, the first three are individual soldier training subjects, and the fourth and fifth two are collective training subjects. I hope you will study hard and do more training after class. Next, I would like to ask Instructor Yan to demonstrate the first training subject crawling forward. ”

Instructor Yan walked to the center of the queue and said to the students: "Creeping forward is a one-soldier combat subject, which is convenient for stealthily approaching the target and launching a surprise attack. This combat subject is very important, and I hope that you will carefully watch the demonstration actions. Instructor Yan turned to the right and turned sideways to everyone. Probably to let everyone better see Instructor Yan's demonstration movements. Instructor Kan gave the order: "Lie down." Instructor Yan fell straight to the ground face down, and the moment he fell to the ground, his left elbow hit the ground, and his body fell sideways on the playground. Instructor Kan gave the order: "Creeping forward." Instructor Yan lowered his head, landed on his right elbow, moved his body forward with his elbow, and curled his two thighs forward, advancing like a snake.

Instructor Yan crawled forward three meters away, and Instructor Kan gave an order: "Charge." Instructor Yan quickly stood up and ran forward quickly. A series of movements, done neatly. Looking at the male and female students in our class, they all looked embarrassed. Instructor Kan said, "Have you seen it clearly?" The classmates said in unison, "I don't see it clearly." ”

Instructor Kan said: "Okay, now please ask Instructor Yan to give an order, I will demonstrate it to you again, please take a closer look." Instructor Yan gave the order, and Instructor Kan broke down the action like Instructor Yan. After Instructor Kan broke down the action, everyone did see the action clearly, but everyone was even less confident to do this action well. Instructor Kan seemed to see the students' thoughts, and said loudly: "Please rest assured, as long as you follow the essentials of the actions we demonstrate, there will be no accidents. ”

At this time, a voice came from the westernmost part of the girl and said, "Report to the instructor, let me try." Instructor Kan said: "Martial arts classmates are out of the ranks. The martial arts classmate said loudly: "Yes." "Take three steps forward, all to the front of the queue, and run to the middle of the queue. Raise your right hand and salute and say, "Please ask the instructor for guidance." ”

Instructor Kan said: "Turn right, prepare for ......" The hearts of the students all rose to their throats, and they all sweated for the martial arts students.
