On the defense line against alien creatures, Bob is fighting bravely in his own power armor.

The armor piercing incendiary bomb ejected from his three barrel heavy machine gun is very efficient in harvesting the lives of alien creatures, so that the burning corpses quickly lay a fire wall in front of the defense line.

This is a recently popular tactic. Armor piercing incendiary bombs are fired from heavy machine guns to kill and ignite the bodies of alien creatures, and then electromagnetic rifles are used to kill other alien creatures illuminated by fire.

This has two advantages. First, it can illuminate the battlefield by igniting the corpse, so that other soldiers can obtain the field of vision and range. At the same time, the igniting corpse is also a natural obstacle, which can cause a certain delay to the attack of alien creatures.

After all, out of biological instinct, alien creatures are essentially afraid of fire. Even under the control of the upper node, these alien creatures do not have the ability to think independently and will be fearless of death.

And the size of alien creatures is huge. Other alien creatures need to climb when they continue to attack. In the process of climbing, it will undoubtedly make alien creatures more conspicuous and easier to be shot.

Looking at a small slope piled up with the bodies of alien creatures, Bob was very satisfied with the killing effect of the heavy machine gun on his power armor.

"Change ammunition!" Bob noticed that his heavy machine gun was about to empty bullets. After shouting, he stepped back two steps. After emptying the last few bullets, he picked up a new bullet chain from one side and loaded it on the machine gun.

A soldier on one side quickly helped Bob remove the original empty bullet chain case and install the new one.

After Bob moved and checked that there was no problem, he nodded to the soldier, took a few steps forward again and rejoined the battlefield.

While pulling the trigger and feeling the shock caused by the bullet, Bob's thoughts suddenly drifted for some reason.

Several months have passed since the end of the three-month service in the joint security maintenance force and returned to the front line. Even the second batch of soldiers trained and dressed in the joint security maintenance force have returned.

These formally trained soldiers, together with the exoskeletons and power armor brought back, greatly improved the combat effectiveness of the original troops in the face of alien creatures, and killed a large number of alien creatures more efficiently.

The improvement of combat effectiveness brought by these soldiers and equipment undoubtedly makes the defense line more stable. The defensive pressure on their defense line is obviously not as strong as before.

At least in Bob's impression, they haven't had an urgent defense in recent months. Almost all problems have been solved by themselves. Compared with before, they have greatly improved and the defense has become a lot more stable.

Among them, the greatest credit naturally belongs to Bob and his soldiers who have changed their new equipment, but at the same time, some credit also belongs to those "knights".

With the establishment of the first knights and the collection of blood tax, the first knights were soon assigned to the defense line to help the defenders fight against alien creatures.

Originally, they didn't care much about this army, which also has exoskeletons, but still uses traditional guns. In particular, they still use the title of "Knight" very retro, which makes people feel that they are just fun.

But Bob didn't think the "knights" were worth laughing at. He just felt that they were useless in frontal combat.

After all, 7.62mm caliber bullets can not penetrate the skin of alien creatures, and can only be used to kill those militants who disturb public security. The weapons of these "knights" are destined to play little role.

However, these Knights also had a good command of self-knowledge, and knew that their weapons suck up, and then they volunteered to take up the work of auxiliary warfare.

Although they were only equipped with ordinary guns, their exoskeletons were no different from others. With the addition of machinery to power, these "knights" soon became very excellent auxiliary soldiers on the battlefield.

Just like just now, it was a "Knight" who helped Bob change his ammunition, which greatly saved Bob's time to change his ammunition.

On the battlefield, one second is enough to decide life and death. It can save time and change direction, which plays a role in improving combat effectiveness.

This also makes these "knights" quickly recognized by the soldiers. Although some people will ridicule them as "knights", they have undoubtedly won the respect of other soldiers.

Bob chatted with the "Knight" while creating another flame slope.

Now there is little pressure on the battlefield. Even if Bob continues to fight, he has enough margin to chat with others.

"Anton, I heard that the second batch of members of your knights are coming soon?" Bob asked the "Knight" next to him after another beautiful shot.

The knight nodded politely and kept working. "Yes, the second batch of members of the regiment who came to pay blood tax will return next week. After that, they will take over our work and continue to provide battlefield support for you."

"That's great!" Bob said after he shot a short shot and killed an alien that missed the wall of fire. "I hope they can be as good as you. When you go back, I'll miss you."

"Ha ha, please rest assured that the members of our knights are very good, and they will make you satisfied." the knight smiled, distributing new ammunition to others and full of confidence in the coming new "knights".

Although the Knights' order has not been established for a long time, and the first Knights' order only has a history of a few months, as a collective, the members of the Knights' order have trained together, so they know each other and have a good degree of trust.

Therefore, this knight will show confidence in the coming New knights, which is the trust in the comrades in arms of the same collective.

Bob nodded without saying anything more, but continued to fight with alien creatures with his mecha team composed of all soldiers equipped with power armor, and every soldier wearing power armor had a knight around him.

The main work of these knights in the trenches was to carry ammunition from the rear ammunition depot, replace ammunition for weapons and equipment such as power armor and heavy machine guns, and assist other soldiers in combat.

Although they were only auxiliary operations, it was obvious that these Knights did a good job.
