Courtyard House: I Rely on Time-Space Trade to Build a Nation

On one side of the valley, several newly erected field tents served as a temporary command post.

The lantern hung high, casting a bright light.

The small space was packed with people, including Commander No. 502, Zhao Ping'an, Xu Yuanshan, several senior staff officers from the East China Field Army Headquarters, and the main commanders in charge of artillery, who had rushed over.

502 sat at one end of the table, holding a pencil in his hand, with a notebook open in front of him, on which the provisional plan that had been discussed earlier was recorded.

Then he gestured for Zhao Pingan to begin.

Zhao Pingan took a deep breath, suppressing his slight nervousness at systematically explaining "future tactics" in front of so many senior commanders for the first time.

Zhao Ping'an knew that his theories mostly came from scattered knowledge from the internet, documentaries, and military forums in the future, and were far from professional. However, some of the concepts contained within them were undoubtedly epoch-making for the army of this era.

Instead of directly discussing how tanks and heavy artillery would charge, Zhao Ping'an first picked up a map from the table and slowly unfolded it in front of everyone.

This was not a typical, somewhat rough military sketch, but a large-scale military topographic map of Jinan and its surrounding area with extremely high precision and incredibly detailed topographic markings. Mountains, rivers, villages, roads, and even contour lines were clearly distinguished, and even the heights of some important city walls and some firing positions were marked. This map was generated by the system after Zhao Ping'an had previously conducted reconnaissance using infantry radar and other reconnaissance equipment.

"Comrades and officers, I, Zhao Ping'an, haven't fought many battles. The only one I can count on is the uprising and the betrayal by our 'friendly forces' at the time. I have some humble opinions on this, and I hope they can provide you with some insights." Zhao Ping'an pointed to the map.

"If you want to do something well, you must first have the right tools."

To win a war, you must first understand the battlefield clearly and thoroughly.

This is the latest detailed map of the Jinan area that I obtained through special channels.

This picture alone caught the attention of the staff officers and commanders present, who all crowded around to examine it closely and murmured in amazement.

The map's level of detail far surpasses any version they have used before.

"Look carefully, and look far and clearly." Zhao Ping'an gestured to Liu Dazhu and another soldier to bring over several boxes and open them. Inside were rows of military high-powered binoculars, artillery telescopes (artillery observation telescopes), and even several individual reconnaissance radars.

"These are the 'eyes' and 'ears' that enhance battlefield awareness. Telescopes and artillery scopes can establish forward observation posts and accurately determine the location of enemy fire points and fortifications."

"And this kind of individual 'radar'," Zhao Ping'an patted the metal box,

"It can detect the movement of enemy personnel and vehicles at a certain distance, reducing the risk of our reconnaissance soldiers getting close and providing early warning of enemy counterattacks or troop movements."

He then took out a mechanical artillery firing data calculator, similar to a large slide rule but with a more complex structure, featuring a dial and slide rule, along with several corresponding firing tables.

"Even with precise target coordinates, accurate artillery fire still requires rapid and precise calculations."

This tool can help artillery staff quickly calculate firing data for different gun positions, different types of ammunition, and different weather conditions, significantly improving the hit rate and fire response speed of the first round of artillery fire.

Our heavy artillery groups cannot rely solely on sheer numbers; they must also strive for precision strikes, using the fewest shells to destroy the most critical nodes.

Su Yu silently transcribed keywords into his notebook with his pencil, listening intently.

The artillery commanders around them were even more eager, wishing they could immediately take those calculators over and study them.

"Now that we've seen clearly and calculated accurately, the next step is to quickly transmit the information and issue commands precisely."

Zhao Pingan turned around and took out a single-soldier radio and a slightly larger repeater radio from another box, which were already somewhat familiar to everyone.

"We previously provided Higashino with a batch of communication equipment, and I brought another batch with me this time."

My idea is to equip regiments, battalions, companies, and even key assault platoons, artillery observation posts, and tank units with this type of radio.

By establishing a network of relay stations, enemy activity detected at the forward positions can be instantly reported to the command post.

Command orders and artillery support requests can reach front-line combat units directly. Infantry, artillery, and tanks no longer rely on signal flares, messengers, and guesswork for coordination; instead, they can communicate, call out, and adjust in near real-time via voice.

Zhao Pingan picked up a single-soldier radio and gave a brief call demonstration.

A clear sound came from another radio station, though it had some static, but the content was unmistakable.

A gasp of air rose from inside the tent!

These senior commanders had long understood the significance of real-time voice communication for battlefield command, but they never expected Zhao Ping'an to want to equip it at the battalion and company level!

"Finally, let's talk about how we use these iron machines," Zhao Ping'an finally steered the conversation back to tanks and heavy artillery.

"Infantry-tank coordination should not be a situation where tanks charge and infantry follow, or infantry charge and tanks watch from a distance."

Close coordination is required. Tanks provide infantry with mobile steel cover and direct fire, clearing machine gun nests and makeshift fortifications;

Infantrymen cleared out anti-tank crews for tanks, designated hard-to-observe targets, and provided flank protection. This required rigorous training and real-time communication via radio.

"When tanks are used to attack fortified city walls or large bunkers, they cannot act recklessly."

My suggestion is to utilize their mobility and protection to engage at close range, using 100mm armor-piercing or high-explosive rounds to precisely strike weak points such as the base of walls, firing ports, and bunker doors. Simultaneously, coordinate with heavy artillery for targeted elimination. The tank group should then rapidly advance during the brief intervals between artillery fire to widen the breach.

Zhao Ping'an's account was not particularly profound or mysterious; in fact, some parts of it had a distinctly "theoretical" feel, reminiscent of later military science programs, and lacked polishing in terms of practical combat details.

However, for those accustomed to the "firepower preparation, infantry charge, bayonet charge" model, where coordination relied heavily on tacit understanding and experience, and information transmission was severely delayed due to equipment limitations, they mostly relied on the advance predictions of the East China Field Army commanders and the on-site command of the division and regimental commanders.

This concept, centered on "information acquisition, rapid transmission, precise strikes, and close collaboration," is nothing short of opening a completely new window.

They quickly grasped all the technical details, and were impressed by the core principles of "clear vision, accurate shooting, seamless communication, and close coordination." The large amount of advanced information and communication equipment provided by Zhao Ping'an ignited numerous tactical inspirations in their minds.
