Liu Dajun is envious of his foreign counterparts, in addition to the Americans, there are also the British Pugwa Comprehensive Training Base, and the Soviet Union's Ashuluk Training Ground, all of which he is looking forward to, but unfortunately, there is no such condition in China.

In the past, there were only 80 tanks, no matter how you look at it, there is no appearance of a third-generation tank, 85 tanks are exported, and they are not used for their own use, and now the 88C tank seems to finally have a modern sense, so he can't wait to come over and ask for it.

Of course, Liu Dajun knew that after the 88C tank completed the finalization test and equipped the troops, the first thing to equip was the main group army after the reorganization, so although his blue army could also come over, it would definitely have to be delayed.

Liu Dajun couldn't wait that long, he was looking forward to being able to have this advanced tank for simulation as soon as possible, so Liu Dajun couldn't help but run over and walk through the back door.

We don't want to, we just help, we are here to help, the tank prototype produced by your machine factory is to be tested, and I happen to have free tankers in my hand to help you test, all kinds of projects, it will definitely not go wrong.

In particular, some dangerous projects, our troops, are the same.

The first place in danger is the tank test gun.

Although it is said to be a mature tank gun, however, there is a probability of everything, and the probability of testing the gun is the largest, and Qin Zhenhua's father was also sacrificed because of the test gun.

The second danger is that the tank has swam across.

Tank troops, relying on high mobility to gallop across the battlefield, this is how the blitzkrieg came, and in front of the tank, not necessarily a flat horse, there are countless obstacles waiting for it, in addition to the artificially created ravines, there are also natural obstacles of mountains and rivers.

Tanks, there are requirements to cross the river.

Since there is this requirement, the next thing is how to cross the river.

If you want a tank to cross the river, it's actually the same as a human crossing the river, you either have to walk over it or swim it.

If you want to walk over, then you have to have a bridge, this seems to be a nonsense, if you don't go through the bridge, you have to swim over, then when you pass, it is estimated that the brain will enter more water.

Don't say that the bridge can't bear the weight, the kind of small bridge that can only bear the weight of five or ten tons will still have countless 100-ton kings passing through. Tanks are also fine.

Moreover, even if there is no bridge, it is possible to build a bridge.

Tank troops have special engineering units, and among the engineers, there are special units that set up pontoon bridges, and tanks also give priority to taking pontoon bridges, and those steel pontoon bridges, after the operation of the engineers, can be erected into the river very quickly, which is still relatively convenient.

In China, a special boat-bridge brigade was specially formed after 80 years, and it is planned that a separate boat-bridge brigade will be deployed in units at the level of military regions and even army group armies. Open the road in the mountains, build bridges in the water, and the front of the army is always a smooth road.

However, in some cases, it is not suitable for bridge-building, for example, the bridge-building force is still far away, for example, in order to achieve the suddenness of the battlefield, it is afraid that the bridge-building will expose the target, at this time, you have to rely on the tank to pass by itself.

In the past, tanks could swim over, and at that time tanks weighed only a few tons, and next to the tank, a special pontoon for floating was tied, and even the most ordinary gasoline barrel could be used to increase buoyancy, and you could swim over.

Don't have a water propulsion? Then it's better to paddle on the tracks, like a landlubber, and it's no problem to paddle over.

However, as the weight of the tank grows larger and larger, it will be inconvenient to pass in the past, after all, it is often dozens of tons, and if you want to float, it is estimated that you have to tie dozens of gasoline barrels, and at that time, it will become a boat.

Therefore, except for amphibious tanks that can float, other tanks can only be submarined.

Diving is like Wei Xiaobao's cheap mother-in-law Li Zicheng in Lu Ding Ji, holding his own Zen staff in his hand, holding his breath from the bottom of the water, and walked to the other side of the river.

The tank does not need to carry a Zen staff, and the tank's own gravity is enough to ensure that the tank can drive steadily through the riverbed under the river bottom, which is similar to walking on the ground, but the tank is not a submarine after all, and it has to do a lot of preparation work if it wants to drive over.

The first is the tightness, inside the tank, there are already various electronic devices, so if the seal is not good, it may flood the electronic equipment inside the tank.

In fact, tanks from the Second World War era began to do this.

Every gap must be sealed, for example, with a muzzle sleeve on the muzzle, a grease or seal around the turret, etc.

However, even if this is the case, it can only ensure that the water does not enter the water in a loud noise, and there will still be small streams of water that will converge, and this is okay, just install a small water pump under the car, and those small water streams will be pumped out.

This problem is solved, but it does not mean that the tank can be launched, so it will suffocate, the engine will suffocate, and the people will also be suffocated, it will have to ventilate.

So, the tank needs a snorkel, this device is very high, like the chimney of a big factory, it is installed outside the hatch of the turret, it goes out of the water, it keeps the air circulating outside, it supplies oxygen to the engine, it also expels gas, and it also gives people breathing.

Of course, this device can't be particularly high, if it is high, it will be unstable, generally about a few meters, and if it is deep, you can only wait for the bridge to be built.

Floating and diving together constitute a swimming crossing, and swimming is dangerous.

After all, the tank is underwater, diving a few meters underwater, who knows what is under the water, it should have been a flat riverbed, maybe it will encounter a big rock, if it encounters a big stone, it is good to say, but it is just a hit, what if it encounters a big pit? I drove in all of a sudden, and all of a sudden, there was no shadow, only the bubbles that floated up.

Therefore, when carrying a long pipe, like a forest-like tank troops, there will generally be a pathfinder in front, and after the first tank is sure that there is no problem, the latter will drive along the road in front of it in turn.

In addition to these natural threats, the tank itself also has dangers, such as failing to seal well, suddenly boiling river water pouring in, such as the engine suddenly not giving strength, stopping halfway, not starting no matter what, etc., in short, the danger of swimming is very great.

Now, Liu Dajun's confidence is full.

Although there is a river in the grassland city, the Yellow River, the mother river of the eastern power, flows from the grassland city, but after all, this river is too wide, often hundreds of meters wide, and it is really not suitable for adventure. At the He Rizhu base, there is a suitable river, which happens to be used as a swimming test site.
