According to the Federal Olympic Association, swimming is one of the most physically demanding sports. Pen % fun % Pavilion www.biquge.info

Because when a person swims in the water, both arms stroke and both legs hit the water or kick the water, the muscle groups of the whole body will participate in the exercise, so the muscles of the whole body can be well exercised. In addition, because the resistance and heat transfer performance of water are greater than that of air, the human body loses heat in water more than 20 times faster than in air, which can effectively consume heat, so the body consumes more energy in water than on land. This energy supply depends on the consumption of sugar and fat in the body to maintain the replenishment.

Nearly five kilometers of freestyle is over, Yang Lei held a submachine rifle in his hand, stood on the amphibious infantry chariot, ordered everyone to rest for five minutes, but could not sink, therefore, more than a dozen fighters were like sponges floating on the sea in a backstroke posture, but there were no landlubbers among these people, on the contrary, a few of them had also won a good ranking in the cadet swimming competition.

As one of the important weapons of the Chinese Marine Corps, the amphibious infantry combat vehicle is extremely versatile, he can not only play a role in the ocean, it belongs to the Chinese Empire amphibious armored vehicle family series, but also equipped with a Tsarist period of Sipnov machine gun, the caliber can reach 30 mm, and there is a Red Arrow-73A anti-tank missile on both sides of the turret.

At present, the amphibious infantry combat vehicle of Huaxia can be divided into four models, one is an amphibious assault vehicle, which is used for beach landing and beachhead impact, and the second type is an amphibious infantry fighting vehicle, which is mainly used for head-to-head confrontation when encountering large-scale enemy forces in the sea area, or using the strategy and tactics of roundabout encirclement, and the third type is an amphibious armored command vehicle, that is, the one under Yang Lei's feet today, in comparison, its firepower configuration is not as rich as the first two, but it has enough self-protection ability and a solid armored body, I am afraid that on the battlefield, Only deep-sea torpedoes can pose a threat to it, and there is also a fourth type, that is, amphibious armored rescue vehicles.

It can be said that in the naval forces, these four infantry vehicles are equivalent to the mechs of the mecha of the mecha combat unit, and even they are more practical than the mecha in some cases.

The reason why the amphibious infantry vehicle can walk on thin ice on the sea surface and move freely is because there are six load-bearing wheels on each side of the hull, which can be retracted during water navigation time to fold the tracks to reduce the resistance of surface navigation.

At this time, Yang Lei was standing in the left cabin of the power cockpit, he looked at the function keys on the dashboard that were much simpler than the mecha, and with a slight click, the engine in the right cabin suddenly roared, yes, the entire right cabin was specially set up for the extra-large engine, and it was less than a meter away from the driver's seat, you can imagine how loud the noise was, but fortunately, find a music CD, Yang Lei blew the dust on the surface, and sent it into the player.

With a passionate march, the turbine in the body of the infantry chariot also began to keep urging the tracks to rotate, the waves were caught between the steel chains, and were sprayed out, and the originally calm sea was suddenly stirred into a white foam, and the soldiers looked at Yang Lei who drilled out of the roof of the car, crying bitterly.

"After the rest is over, the imps, continue your devil's journey!"

"Dada-da-da!"

While speaking, Yang Lei's index finger pulled the trigger in his hand, and the next second the bullet began to pass through the ears of these people, everyone saw this, and rushed back, desperately fleeing in the direction of the beast camp, Yang Lei changed the infantry chariot to an automatic state, and then drilled out of the head, but in the blink of an eye, the soldiers had swam out of dozens of meters, looking at these soldiers who were like refugees seeing the new world, Yang Lei showed a treacherous smile that the conspiracy succeeded.

He knew that in addition to exercising a physique that surpassed ordinary people, it was also necessary to focus on cultivating the strong will of these warriors, and the reason why he did this was nothing more than to create a sense of urgency in the psychology of everyone. In fact, the machine gun used by Yang Lei is not a live ammunition, but a very small empty cartridge, but despite this, if it is hit, with the strong thrust of the chamber, it can still make people's bodies quickly red and swollen.

Therefore, the team members must rely on their own instinctive awareness of danger to dodge, listening to the gunshots in their ears, will also let them experience the feeling of bullets on the battlefield, and can face it calmly in the future actual combat.

The soldiers who were struggling to wave their arms forward, when they looked back, Yang Lei was standing in the car staring at them, and suddenly couldn't help but shiver, but as soon as they stopped, the rapid gunfire would sound in their ears, coupled with the splashing of water that was hit by bullets from time to time on the surrounding sea, everyone invariably sped up.

"Hurry up, hurry up...... Are you ducks?! Yang Lei said: "The ducks are faster than you, and when you swim past the ducks, you can end this kind of training!" ”

Swimming through ducks? They don't have the big, thick fins, and they don't have a backache when they stand and talk...... Seeing Yang Lei, who was standing on the chariot riding the wind and waves, with a momentum like a rainbow, the soldiers thought in their stomachs.

Finally, just when everyone was depressed and felt that they had nothing to love, the distant sea level had begun to faintly emerge from the land, followed by the beach and the barracks that had been preliminarily rebuilt.

"There is still one nautical mile to go to the camp, I declare, the last ...... to arrive at the camp Ten kilometers off-road! Looking at the fighters who were still sluggish thinking about their words, Yang Lei shouted: "Now, the game begins!" ”

At the sound of an order, the soldiers who reacted began to use their last strength to quickly surpass the torrent in front of them, and some even didn't look at the direction at all, and waved their strong arms desperately, until they looked up and found that they were swimming in the wrong direction. Obviously, a straight line is always the shortest distance, and after a while, some soldiers have already closed the distance to the beast camp by half the distance, but they have discovered a terrible truth.

Why...... Why does the camp still seem so far away from me, is it a mirage? Wrong! At this time, someone has already thought of the answer.

It's very simple, when Yang Lei told them the current position just now, it must be calculated according to the coordinates of the built-in radar system of the infantry chariot, but you must know that whether it is an international map or a coordinate, the units that express the distance in the sea are all used in the nautical mile!

Nautical miles, kilometers, worlds apart...... No wonder I haven't seen the barracks yet, it turned out to be a mistake, now everyone is not swimming, not swimming, and they are in the dilemma of making a choice, one kilometer is equal to one-half of a nautical mile, that is to say, one nautical mile in Yang Lei's words is almost equivalent to two thousand meters on land, and now there is only one kilometer left.

Yang Lei looked at everyone with a smile and said: "Wangmei quenches thirst, the famous tactics that inspired the fighting spirit of the soldiers in ancient times in my country, do you need me to tell you the story behind it?" ”

This...... This guy turned out to be on purpose?! (To be continued.) )
