You were tasked with guarding the Sihang Warehouse, and you brought out a Tiger tank?

The security regiment's headquarters, the training ground on the east side.

Under the blazing sun, the loess soil turned white from the heat, and waves of heat rose up.

More than three hundred militiamen, including former defeated soldiers and newly recruited soldiers, were shirtless, sweating profusely, digging trenches.

"Dig deeper, at least one and a half people high."

Zhao Dashan stood in a newly dug trench and shouted at the top of his lungs.

He was wearing a khaki military uniform, but the sleeves were rolled up to his elbows, and his face and hands were covered in mud.

Several militiamen surrounded him, listening to his explanation.

In several other locations, system engineers serving as instructors were giving explanations.

"See that? You can't dig a trench in a straight line; you have to dig it in curves, like a snake crawling."

Zhao Dashan drew a winding line on the ground with his foot:

"Why? Because the Japanese planes strafed the trenches. A whole magazine of bullets would go from one end to the other, and that wouldn't be enough to kill any number of people. The artillery shell fragments were the same; they could fly a long way in the barrel."

He paused, then pointed to the excavated soil:

"Don't just pile this soil up haphazardly. Put it in sacks and stack it on both sides of the trench to protect your body. Especially for machine gun emplacements and grenade launcher emplacements, the front and back sides need to be reinforced to protect against shrapnel."

One of the militiamen scratched his head:

"Instructor Zhao, aren't we a security regiment? Why are we digging trenches? We're not going to fight a positional war."

Zhao Dashan glared at him:

"Aren't the security regiments soldiers? Are you going to use fire pokers to block the Japanese when they attack?"

The soldier shrank back and dared not speak.

Zhao Dashan jumped onto the ground and surveyed the entire arena:

"Listen up, everyone. Defense is simpler than offense, but it's not about blindly digging with a shovel. A well-dug trench can stop bullets, shrapnel, and shockwaves. A poorly dug trench is like digging your own grave."

This is why Lin Feng insisted on training them in digging first. Time was limited, and the upcoming main battles would primarily involve the Japanese attacking while the Xia army defended. It was good to let these militiamen learn defensive techniques first, so that when they actually entered the Battle of Shanghai, at least their sacrifices wouldn't be in vain.

"Keep digging. If we don't finish today, we won't get any food."

The soldiers quickly lowered their heads and worked hard.

The sounds of shovels and hoes striking the earth and rocks, along with panting and cursing, blended together.

Lin Feng stood under a tree not far away, watching the scene.

He was wearing a military uniform, but no hat, and in his hand was a copy of the "Infantry Drill Manual" revised in 1935, which he had found in the original owner's room. The pages were yellowed.

While watching, I compared the explanation with Zhao Dashan's.

To be honest, in his previous life he studied science and engineering at the National University of Defense Technology. Although he had participated in military training, it was limited to target practice, drills, and basic tactics.

He only had a superficial understanding of the construction of field fortifications during World War II.

He knew that trenches should be dug in a sawtooth or curved shape to protect against artillery fire, that there should be anti-artillery holes and communication trenches, and that the accumulated soil should be used for reinforcement.

But he had to learn the specifics of how to dig, the angle, how to drain water, and how to prevent landslides.

"We mustn't be complacent..."

Lin Feng closed the manual and silently reminded himself.

He had a vision that transcended his time, knowing the course of history and the direction of future warfare.

But specifically in this era, he still has a lot to learn about tactics, equipment, and logistics.

It's easy to talk about war on paper, but when it comes to actually leading troops into battle, people will die.

After watching for a while, he turned and left the training ground.

-----

Back at the command post, which was actually just a slightly more decent tile-roofed house.

Lin Feng closed the door and took out the captured gold and silver from the system space.

Ocean silver, silver ingots, small yellow croaker, large yellow croaker.

Then connect your mind to the system.

"System, recharge."

[Rechargeable items detected, calculating...]

Total redemption points earned: 156 points

Current exchange points: 172

I had some exchange points left in Erlong Mountain, plus a few captured guns with worn-out rifling in the past few days, so I collected this much.

The biggest prize was the large yellow croaker, which is essentially a gold bar; these things are valuable.

He opened the unit exchange list.

[Exchange for 10 basic Nationalist Army infantry squads, costing 80 points]

[Exchange for 4 basic Nationalist Army heavy machine gun squads, costing 40 points]

[Exchange for 2 basic Nationalist Army grenade launcher sets, costing 12 points]

Total points consumed: 132

Current exchange points: 40

148 new soldiers appeared on the open ground outside the tile-roofed house. The local militia were all training in the distance. Apart from the system soldiers on guard, no one noticed the sudden appearance of these new soldiers.

Including his original troops, he now has 22 infantry squads, 3 engineer squads, 6 heavy machine gun squads, and 4 grenade launcher teams.

Referring to the idealized organization of the main force division of the National Revolutionary Army in his memory, Lin Feng began to reorganize two infantry companies and his directly subordinate units, taking into account the basic organization of the Japanese.

Three infantry squads form a platoon, and three platoons form a company. Each platoon is reinforced with a heavy machine gun squad, and the company headquarters directly commands two grenade launcher groups.

Thus, a company would have 9 light machine guns, 2 heavy machine guns, and 2 grenade launchers.

The firepower is quite considerable.

It's important to know that during this period, the standard equipment for a squad (equivalent to a platoon) of a Japanese Type A division was 3 Type 11 light machine guns and 2-3 grenade launchers.

A company (equivalent to a reinforced company, about 240 people) would have a machine gun squad assigned to a battalion (equivalent to a company), equipped with 2-4 Type 92 heavy machine guns.

Lin Feng's company had the same number of light machine guns as the Japanese, and about the same number of heavy machine guns, but slightly fewer grenade launchers.

However, considering that the Maxim gun's sustained firepower far exceeds that of the Japanese Type 92, it is not at a disadvantage in actual firefights.

"We also need to strengthen logistics..."

Lin Feng stroked his chin, thinking.

Heavy machine guns and grenade launchers are both heavy ammunition consumers; once fighting starts, ammunition is consumed very quickly.

Once the exchange points are more readily available, we need to equip each company with six horse-drawn carts specifically for transporting ammunition and supplies.

As he was thinking, he suddenly remembered something.

Can a heavy machine gun squad be upgraded too?

With a thought, he stepped out of the house and looked at the newly exchanged Nationalist Army heavy machine gun squad.

Should the basic heavy machine gun squads of the National Revolutionary Army be upgraded?

really.

Two options will pop up below:

[Upgraded to - Basic Hans-equipped heavy machine gun squad (6 men)]

[Merit Points Required: 15]

【装备：MG34通用机枪（备弹3000发）、2.5倍瞄準镜、三脚架、对空用三脚架、对空用瞄具、P08手枪×2（每人配弹40发）、毛瑟98k步枪×2（每人配弹160发）、烟雾弹等】

[Training Level: Excellent (Suppression fire, overtaking fire, anti-air fire, and other tactics)]

[Upgraded to - Basic White Eagle Equipped Heavy Machine Gun Squad (6 men)]

[Merit Points Required: 15]

【装备：M1919A4式重机枪（备弹3000发）、三脚架、M1911手枪×6（每人配弹40发）、M1903春田步枪×2（每人配弹160发）、烟雾弹等】

[Training Level: Excellent]

Logically, Hansband should have been chosen, as ammunition resupply is convenient.

But a thought suddenly popped into Lin Feng's mind.

Since there is basic White Eagle equipment, is there any advanced version?

Just like a tech tree in a game, you have to unlock the later ones after you complete the previous ones.

If he were to upgrade to the famous Lao Gan Ma chili sauce, he would be making a fortune.

He decided to give it a try.

"System, upgrade a basic ROC Army heavy machine gun squad to a 'Basic White Eagle Equipped Heavy Machine Gun Squad'."

[Consumes 15 merit points]

[Upgrading...]

A flower in front of you.

The equipment of the six soldiers in the heavy machine gun squad standing in the yard changed instantly.

The khaki military uniform was replaced by an olive-brown M1941 field uniform, and he wore an M1 steel helmet.

The Mauser C96 pistol slung at his waist has been replaced with an M1911A1, and even the holster design has changed.

The water-cooled Maxim heavy machine gun placed next to it has been replaced by an air-cooled M1919A4 with a tripod, a thinner barrel, and no longer has a thick water-cooling sleeve.

The entire class had a different vibe.

Lin Feng focused his attention and looked at the class again.

【Ding! 】

A system notification sounded.

[Upgradeable unit detected: Basic White Eagle Armored Heavy Machine Gun Squad]

[Should we upgrade?]

really.

Lin Feng was secretly delighted.

There is only one option on the interface:

[Upgraded to - Advanced White Eagle Equipped Heavy Machine Gun Squad (6 people)]

[Merit Points Required: 8]

【装备：M2HB大口径重机枪（备弹1500发）、3倍瞄準镜、三脚架、M1911手枪×6（每人配弹40发）、M1903春田步枪×2（每人配弹160发）、烟雾弹等】

[Training Level: Excellent]

M2HB.

Lin Feng's eyes lit up.

He knows this thing too well.

Browning M2 heavy machine gun, nicknamed "Old Godmother", uses 12.7×99mm large-caliber ammunition, with an effective range of 1800 meters and a maximum range of over 3000 meters.

At a distance of 600 meters, a conventional bullet can penetrate a 30-centimeter-thick layer of sand and a 60-centimeter-thick layer of clay.

If it were an armor-piercing projectile, it could penetrate 21 millimeters of armor steel at a distance of 500 meters, and still have a penetration depth of 14 millimeters at 1000 meters.

Dealing with those Japanese "bean tanks" with only 12 millimeters of armor was like opening a can.

Not to mention it can also take down Japanese cavalry armored vehicles, railway armored vehicles, and even low-flying aircraft...

It's basically a small machine gun.

"This is good stuff."

Lin Feng muttered to himself.

Upgrading from a basic Nationalist Army heavy machine gun squad to an M2HB squad requires a total of 23 merit points (15+8).

It's a bit pricey, but worth it.

He currently has 85 merit points. Upgrading three squads will give him 69 more points, which is just enough to increase his firepower.

He would naturally have direct command of these three upgraded M2HB squads, just like the three engineer squads, and they would serve as the spearhead of the attack.

As for the two reorganized system chains, they can only spend another 30 exchange points to exchange for three new water-cooled Maxim squads.

As for the regimental soldiers who were currently training, Lin Feng planned to select the best and discard the worst. After two weeks of basic training, they would be reorganized. The outstanding ones would be kept, while those who were not physically fit or not quick-witted would be sent to the logistics units.
