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

Lin Feng quickly did a mental calculation.

In the system, the most basic [Basic National Army 82mm Mortar Squad (6 people)] only requires a mere 8 exchange points.

According to the system's exchange rate, that's 400 silver dollars.

Before the full-scale outbreak of the War of Resistance against Japan, the Shanghai-made 82mm mortar produced by the Jinling Arsenal had a factory price of 487.2 silver dollars per mortar and 5.8 silver dollars per shell.

What time is it now?

With the fall of Shanghai, Nanjing was lost.

The most important military factories of the Great Xia Dynasty are being desperately moved to the rear area of ​​the mountain city.

In the short term, it is simply impossible for Daxia's military industry to produce new Shanghai-made 82mm mortars.

Heavy firepower for frontline troops is extremely rare; once it's destroyed, it's gone forever, and there's practically no market for it.

Scarcity drives up value, so doubling the price is perfectly reasonable, right?

Lin Feng stroked his chin and decided to sell the mortar he had bought for 400 silver dollars in the system to Wang Tianlu for 800 silver dollars each.

Moreover, even if he priced it at 800 silver dollars, Wang Tianlu could still make a very high profit margin by reselling it to the ragtag troops in the Fifth War Zone that were extremely lacking in firepower.

Those generals of the Sichuan Army and the Northwest Army would absolutely be willing to sell their possessions to buy it in order to save their lives.

In this way, the profit he makes from selling each mortar is enough for him to get another one for his troops for free through the system.

Others provided the money to support his army.

This business is incredibly profitable.

After calculating the economic costs, Lin Feng refocused his attention on firepower configuration.

After these adjustments

The battalion-level units of his three divisions will be heavily equipped with 81mm mortars.

In terms of firepower density, it could easily suppress the two 70mm Type 2 infantry guns and several grenade launchers equipped by a Japanese battalion of the same level.

At the regimental level, it possesses four 120mm heavy mortars.

In terms of both range and power, it could absolutely blast the four to eight 75mm mountain guns equipped by a Japanese regiment of the same level into oblivion.

So, what about the division level?

The division level corresponds to the Japanese brigade.

如果是鬼子的独立混成旅团，一般下辖2到3个炮兵中队，装备12到18门75mm野炮或山炮。

The goal is to achieve absolute dominance in artillery battles at the division level.

Therefore, each of our divisions must be equipped with a powerful artillery regiment with 24 to 36 cannons, just like the previous Provisional 50th Division.

Thinking of this, Lin Feng had an idea and clicked the redeem button again in the system.

"Whoosh!"

A gun crew equipped with old-fashioned 75mm Krakow mountain guns suddenly appeared on the parade ground.

Without hesitation, Lin Feng spent 80 merit points to upgrade it to the high-performance [Bofors M1930 75mm Mountain Gun Squad].

He stared intently at the brand-new Bofors mountain gun before him, and the system interface once again displayed the upgrade option.

Sure enough, it can be upgraded further.

Moreover, two different branch routes emerged.

Lin Feng clicked on the detailed data for the first option:

[Upgraded to - Basic Nationalist Army 105mm Mountain Artillery Squad (24 men)]

[Merit Points Required: 240]

【装备：博福斯 L12 105mm山炮×1（配弹×40），弹药马车×1，骡马×8】

[Note: This 105mm mountain gun, manufactured in Bluetooth country, uses the same gun mount as the M1930 75mm mountain gun. The caliber has been increased, but the weight remains the same, resulting in excellent performance in extremely cold and mountainous environments.]

Lin Feng carefully studied the data of this 105mm mountain gun.

相比于博福斯 M1930 75mm山炮，它的炮管长度从L22缩短到了L12，这导致它的最大射程从10.1公里，缩短到了7.5公里。

However, the compensation for the shorter range is a sharp increase in firepower.

The diameter increased from 75mm to 105mm.

The weight of the warhead also doubled from 6 kilograms to 12 kilograms.

Doubling the amount of explosives means doubling the explosive power.

What excited Lin Feng even more was that this was a mountain gun.

The overall weight of this 105mm artillery remains around 850 kilograms.

Compared to those 105mm howitzers that weigh one to two tons, it is as light as a toy.

In the original timeline, General Mann's troops used the mobility of this lightweight artillery to inflict heavy losses on the Soviet Union during the Winter War.

In addition, this mountain gun can be disassembled into several parts, each weighing between 100 and 120 kilograms, when on the march.

They were carried directly on packhorses during marches, traversing mountains and valleys as if walking on flat ground.

This was a godsend for the Great Xia's domestic battlefields, which had extremely poor road infrastructure and numerous mountains and rivers.

Lin Feng then selected another upgrade path that focused on range specialization:

[Upgraded to - Basic ROC Army 75mm Field Artillery Squad (12 men)]

[Merit Points Required: 180]

【装备：博福斯 M1929 75mm野战炮×1（配弹×40），弹药马车×1，挽马×12】

[Note: This is a 75mm field gun produced in the Bluetooth country, towed by mules and horses, with a range far exceeding that of similarly used Japanese artillery.]

Upon seeing this cannon, some historical information came to Lin Feng's mind.

This cannon was a key consideration for the Jinling Military Industry Bureau when selecting artillery pieces for military use in 24.

It was included in the final shortlist along with the French Schneider 75mm field gun.

Its performance is indeed excellent, employing mule-drawn traction and achieving a barrel diameter of L40.

The projectile weight remains at 6.5 kg, but the extra-long barrel provides a maximum range of up to 14 km.

This range allows it to suppress all of the Japanese 105mm howitzers and 75mm field guns at long distances.

However, Lin Feng couldn't help but click his tongue when he looked at its weight data.

The weight of the cargo is 1.55 tons!

It is almost twice as heavy as a 75mm mountain gun.

"This cannon's cost-effectiveness is a bit low."

Lin Feng shook his head, silently calculating in his mind:

The Le.FH18 light howitzer, with a caliber of 105mm, also weighs 1.5 tons.

Although the Hans howitzer has a shorter range of only 10.5 kilometers, it has a thicker barrel and greater power.

Moreover, a 1.5-ton artillery piece would be unable to pass through the dilapidated roads of Daxia if it encountered even a little mud or a simple bridge.

It would require at least six strong draft horses linked together to pull it, which would put too much logistical pressure on several infantry divisions.

In comparison, the Bofors L12 105mm mountain gun offers better value for money.

It has the firepower of a 105mm caliber gun and the light mobility of a mountain gun.

It can be deployed in large numbers to several infantry divisions as the core suppressive firepower.

After careful consideration and weighing of the options.

Lin Feng ultimately made the decision to equip each of his three infantry divisions with a deluxe, reinforced artillery regiment.

Taking into account the logistical supply capacity of mules and horses at the division level.

The organization of this divisional artillery regiment is as follows:

It has two battalions of 12-gun Bofors M1930 75mm mountain guns each.

And a battalion of eight Bofors L12 105mm mountain guns.

The entire regiment has a total of 30 artillery pieces.

Including gunners, ammunition handlers, logistics personnel, and grooms, a fully-equipped artillery regiment requires 1192 people and 240 mules and horses.

"Three divisions, that is, three heavy artillery regiments like these..."

Lin Feng stared at the cannon on the parade ground, its surface gleaming with a cold metallic sheen, his eyes burning with fierce fighting spirit.

In terms of firepower.

His current artillery firepower, equivalent to that of a division, will completely overwhelm the Japanese independent mixed brigade.

Even against the most elite regular Class A division of the Japanese army, he would not suffer too much loss in a firefight.

"Kunisaki Noboru is just an appetizer."

Lin Feng clenched his fists and turned his gaze northward toward Pengcheng:

"Wait until my artillery regiment is fully formed."

"Itagaki Seishiro, Isogai Rensuke... you old devils, just wash your necks and wait to be bombed."
