Behind the window of the building, Claudia was looking at the sky worriedly, when suddenly, she felt the strength of John's hand increase, and the temperature of the palm became as hot as a flame.

Claudia looked at John, saw those eyes that seemed to be burning, and asked, "John, what's wrong?" ”

John uttered something that froze Claudia in place: "I thought of a way to restore communication. ”

Claudia was a little confused, John was an armored soldier before, he didn't understand communication technology, and now those experts in the technical department are in a hurry, what can he think of? But out of trust in her childhood friend, she asked, "How?" I can help you with the reference. ”

John rubbed his chin, organized his words, and said heavily: "Luo Wei's death row camp, do you know how they command the troops? ”

Claudia didn't understand this, and said a little confused: "Psionic one? ”

"This should be the most efficient method, but the death row camp is not, because Luo Wei has never found a suitable psychic person to cultivate among the death row inmates." John tugged at his military uniform, pointed to a piece of colored fabric, and said, "I've read in the intelligence department's research reports that the practice of death row camps is very primitive, and that is the 'flag'!" Use flags of different colors, horns of different frequencies, and combine them together for command. ”

Banner! For the high-tech federation, this is simply an antique-level or even primitive-level command method, but you have to laugh off other people's big teeth when you say it in normal times, what age is it, there are so many satellites in the sky, and there are still flags?

But if you think about it, when high-tech communications lose their effect, all the military becomes "blind", but are they really blind? No! Their eyes can still see, their ears can hear, and the flag command does not require any technology, as long as you have eyes and ears, and that's enough!

Claudia thought for a moment and said dumbfoundedly, "You want to emulate the command style of the death row camp?" ”

John nodded heavily, "That's right. ”

"But—" Claudia bit her finger and quickly said something wrong, "However, no one in the front-line commanders of the Federation can read the flag, and it takes a long time of training, otherwise there is no way to understand what flag means and what command a few trumpets mean." ”

John did not deny it: "Yes, we can't convey the flag as accurately as we do in a death row camp, and we don't even have a flag or a horn, but we have you!" ”

Claudia was a little confused: "Me? ...”

"Yes, we have you!" John grabbed Claudia's hand and said firmly, "You only need to do one thing, go to the warehouse and find the paint, inject it into the propulsion system, and then swipe across the battlefield and control the trajectory so that the paint will take on the symbol I specified in the air!" ”

"This... I can do... In the past, when I trained, I had a fixed path to fly. Claudia's expression was still a little confused, she looked at John, and whispered, "But it's still the same problem, even if I can draw a symbol in the air, how can I make the commanders understand the meaning of the symbol in a short time?" ”

"That's the core problem, our symbols have to be simple, minimalist! I wanted to be able to communicate instructions in a way that everyone could understand, so I chose the traffic light! We refer to the traffic lights! Just imagine, when you see the three colors of red, yellow, and green in the sky, the first reaction of a normal person is to stop with red, stand by yellow, and move forward with green! I'm sure those commanders will understand this in a very short time! So, we use the colors of red, yellow and green to represent the course of action, which represent garrison, standby, and attack, and then use symbols to represent the troops and the area of action! John clenched his fists and muttered, unable to find a pen for a while, so he simply buttoned the pattern on the wall with his fingernails, "You see, for example, if we want the 1st Division to launch an attack on the B2 position in the Circumsea Theater, then use green paint and draw in the air: 5DIV-B2."

Immediately afterward, John drew another mark: "If you want to subdivide it, for example, let the 2nd Battalion of the 5th Division stand by, then use yellow paint and draw 5DIV-2Bat in the air."

"For another example, if we want a certain unit to evacuate, for example, the 11th Division is blocking someone else's way, or has suffered serious losses and needs to evacuate to the L21 area to hold on to repairs, we will use red paint to draw in the air: 11DIV-L21."

Looking at the examples carved on the wall, Claudia was stunned, she glanced up and down for a while, and said in a trembling voice: "It's feasible!" Those commanders may not understand at first, but it only takes a very short time to get used to it, and they will understand that this is a command signal! ”

John grabbed Claudia by the shoulder and said firmly, "That's right! The communication system collapsed, the army was already blind, but the commanders were not blind! They can't receive satellite signals, but they can see ours with the naked eye! I can't guarantee how precise this instruction will be, but it's better than standing still! ”

Claudia subconsciously held John's arm, her eyes wandering, and she said with some concern: "But... But! It also means one thing, our commander can see it, the empire can also see it, and our command will be fully exposed! ”

"That's not a problem! For the area numbers of the Circum-Sea Theater of Operations, our commanders are more familiar with it than with the Empire! Mobilize faster! Even if the opponent is just as fast, it's a big deal to have a head-to-head duel, the Guardian of the Motherland is a tank designed to deal with fierce beasts, the frontal armor is weak, if it is a positional battle, not to mention the monarch-level main battle tank, or the giant god main battle tank, even ordinary self-propelled artillery can easily destroy the Guardian of the Motherland! ”

Looking at John, whose eyes were hot, Claudia didn't ask any more questions, and she only said four words to her childhood friend, who had been protecting her since she was a child: "I believe in you." ”

"Thank you for your trust." John hugged Claudia tightly, and then said, "Time waits for no one, you go to the warehouse immediately, find the three colors of paint, and then contact me with the private frequency band, I will call up the real-time combat map in the command room, analyze the current battle situation, and finally tell you what to do!" ”

Claudia's eyes were not confused, full of trust and firmness: "Understood! ”

Just as Claudia was about to leave, John suddenly grabbed her hand, looked into her eyes affectionately, and said faintly: "This time, promise me, don't mess around like the Arctic Crisis, I can't live without you, I really can't." ”

Claudia pursed her lips, nodded heavily, and walked away quickly.
