The defense line of the barbed wire mine and fixed robot is sturdy and sturdy, but it lacks flexibility, and the undead can try all kinds of means to attack the defense line without harassment, until the defense line is completely broken through a gap!

If you want to stop this situation, you need to take the initiative to attack, disrupt the rhythm of the opponent, and blindly defending without attacking can not really make the defense line impregnable.

However, it is obvious that the air force alone cannot fully meet the requirements, and many targets need to be eliminated by the army.

But the base does not want to waste its already scarce human resources in the meat grinder in front of the third line of defense.

That's right, many of the positions in front of the third line of defense in Hell Valley were expected to be meat grinders for the bloodletting of the undead army, not core positions that had to fight for every inch of land.

To solve this problem, the Storm base has deployed a group of unmanned vehicles on the front line that can be operated remotely.

On Earth, remotely operated ground combat robots are still at the laboratory stage, and there are always problems with their adaptability to complex battlefield environments and good maneuverability, which constrains their further development.

However, the problem of remote-controlled combat robots on Earth is only a problem for the battlefield environment of Earth, and many problems are not so prominent when the environment becomes Hell Valley on the Anglia continent and the object of war is changed to the undead.

For example, how to ensure the operation of remote control robots in the battlefield environment is a big problem on the earth, electromagnetic interference, hacker invasion, and other problems will never be able to enter the actual combat if they are not solved!

After all, the military of any country does not want to spend a lot of money to get a robot army to be reimbursed by an EMP, let alone just send it to the battlefield to be stolen by enemy hackers to steal control and turn around and shoot at their own people!

These two items alone are enough for the military industrial enterprises on the planet to scratch their heads - the offensive and defensive methods of electronic warfare are always developing rapidly, and no one can guarantee that their control network will be 100% safe, and this cannot guarantee that no matter how powerful the robot is, it is meaningless.

But in Anglia, no one even knows what electromagnetic waves are, and hackers don't know that they won't be created until thousands of years later, so naturally there is no need to think about the above problems at all.

In fact, the control technology of the base for those remote-controlled vehicles adopts the simplest civilian technology, which is convenient and easy to use!

Because you don't have to think about security, the development of supporting software is even faster!

Moreover, unlike the Earth battlefield that needs to deal with all kinds of unexpected situations, this batch of remote-controlled vehicles at the Storm Base only needs to meet the special environment of Hell Valley, and there is no need to think too much about it at all.

For example, the robot operated by Rusta was directly modified from a road roller.

Overhauled the cab to allow it to be operated remotely, then welded a layer of steel on the outside, set up some grenade launchers to deal with melee enemies, and everything is OK!

Whether it's dealing with skeleton soldiers or ghouls, this simple and violent thing is the most useful, just put it in a row and rush directly into the skeleton pile, and it will be over when you run over!

However, only this level of force obviously can't solve the higher-level undead, so the generation of god car 59 has also been put on the modification platform.

For tanks, it is not difficult to modify the remote-operated vehicle, but it is difficult to make the stout tank gun work.

You know, the old-fashioned 59 doesn't have an automatic bullet machine!

You can't just stuff a shell in the chamber and shoot it out, right? Not to mention that it is not enough, if you bump a few more times, you may go off, how can this work?

Going straight to the automaton will naturally solve the problem, but then the cost will be too great, and the turret will almost be torn down and redone.

The solution to the base is also simple - directly make a magazine at the end of the gun, four multi-purpose armor-piercing shells, you can't choose the type of bullet, and pull it down after the shot.

Moreover, there are some problems with the matching of the sighting system after the transformation, so the range is much shorter.

None of this is too much of a problem, though, as the main opponents of these RC vehicles are the large number of skeletons and ghouls, and all they need to do is have tracks.

…………………………

Rusta was startled by the licker who had just pounced, but fortunately the tank next to him helped him out of the siege, and he turned his head to look and found that a Chinese man in the 59 double car group not far away gave him a thumbs up.

Rusta stiffly stretched out his hand and gave a thumbs back, thought about it, and said "thank you" in the Chinese dialect he had just learned.

"Don't rush too hard, everyone! Back in the range of the stationary robots in front of the position, you won't be able to deal with the approaching lickers, but they can help you sweep those monsters down! ”

Listening to the instructor's words, Rusta realized that he had indeed rushed a little deep just now, and quickly turned the front of the car and increased the accelerator to retreat in the direction of the position.

Soon, because of the driving too strong, Rusta's roller was targeted again.

This time it was two Death Knights who rushed up, brandishing their sabers with pitch-black flames in their hands.

The saber slashed against the roller's body with a screeching sound, the pitch-black flames rapidly corroded the steel plates, and as the Death Knight's warhorse swept past the body, a shocking scar appeared on the body.

Just as the Death Knight turned his horse's head and was about to give the steamroller another blow, the saber was just halfway through the body when the 730 gun of Guard 1 opened fire a thousand meters away!

The dense rain of bullets instantly burst the Death Knight's horse, and at the same time shattered his lower body, leaving only the upper body struggling there.

However, none of the surrounding undead came to the rescue, but were quickly trampled by the hooves of the other Death Knights.

Rusta's camera was limited in what it could see, and he only saw that the Death Knight was knocked down by a cannonball with a tracer in tow, and then he didn't know anything else - thanks to the power of the 730 gun, the camera on the left side of the steamroller was broken by a stray bullet, and the track seemed to have been accidentally injured, and the car began to spin in place not long after driving forward.

"What the hell!"

Rusta depressedly smashed the operating table with his fist, the track is broken, the car is scrapped, no one goes to the scene to repair the track, and the track will not be connected by itself.

That is, Rusta's mission for the day is over.

But the battle ahead continued, and he needed to stay here and stay on standby.

Just as the undead were being raided by remote-controlled vehicles, three Y-9 gunboats quietly appeared on the battlefield and aimed their guns at the undead who might pose a threat to the vehicles.
