Lord Man's shelling tossed intermittently all night, although the only one that really posed a threat to the crossing crowd fell into the camp and scared Chen Fa'er into spilling beef and radish soup cannonballs, but Lord Man succeeded in keeping the little 100 people, including Kong Heng, in a state of nervousness all night.

The "Merkava 4" main battle tank worked all night with a vehicle-mounted thermal imager, but in the end it failed to find even a trace of the Qing artillery that launched the attack. After sunrise, looking at the ridiculous impact points of the Qing army, Kong Heng affirmed his previous worries about the use of those antique infantry guns in the hands of the Qing army as a reduced range version of howitzers.

"These grandsons aren't really going to use that old-fashioned infantry cannon to play parabolic shelling, are they?" Zhang Zhiqiu asked Kong Heng.

"I guess it's probably like this, judging from the frequency and touching accuracy of the Qing army's long interval of shelling, they may have figured out how to apply the Pythagorean theorem to shelling!" Kong Heng said.

Before the advent of the Gallic chicken's "Miss 75" infantry gun, the artillery in this world except for the crossing of the crowd used all the back guns, and a reset had to be carried out when a shot was fired. In addition, the elevation angle of the infantry artillery is much lower than that of the howitzer, and if the artillery of the new army of the Qing army really wants to play parabolic shelling, it really has to spend a lot of time on the artillery erection, which leads to a very long interval between shelling.

As for the impressive shooting accuracy of the Qing artillery, not to mention whether those artillery soldiers mastered the various parameters of these guns in their hands, in terms of the frighteningly large tolerances of weapons and equipment at the end of the nineteenth century, do you still expect long-range accurate shelling? Maybe the difference between the two shell propellants is one or two in Nima!

"Holy, then we're going to have a sore egg!" Zhang Zhiqiu said that although he was a beauty last night, considering that he had been in the extreme anxiety of not knowing whether the next shell would fall in his foxhole, this kind of glamorous blessing was really unbearable.

"Humph! I don't think that's the worst news, the Qing army's shells used 'yellow powder', that is, picric acid explosives! And not the black powder that the intelligence services have always said. Kong Heng sniffed the shrapnel he had collected and said.

As a middle-aged man who has been dealing with explosives since he became an adult, Kong Heng can conclude by his sense of smell that the shells that fell last night were filled with picric acid explosives, which were far more powerful than black powder.

In 1771, the Englishman P. Wolf was the first to synthesize picric acid. This thing is a yellow crystal, hence the name "yellow powder". Originally, picric acid was used only as a yellow dye in the textile industry, and it was not until 1885 that the French used it to load into artillery warheads.

Of course, at the end of the nineteenth century, the cost of producing picric acid was still very high, and artillery shells filled with picric acid were not used in large quantities by the armies of various countries, and only the British Royal Navy, which was at its peak at this time, had the luxury of equipping such ammunition.

However, in several battles with the foot basin chicken, Maozi and Manda, various explosives have reaped fruitful results in actual combat. This greatly stimulated the generals of various countries. Obviously, the armies of many countries have secretly equipped the front-line troops with a lot of shells filled with picric acid explosives. It is not surprising that the new army, whose main task is to fight against the "pseudo-Song" troops, also followed the trend and purchased this kind of picric acid shells at a high price.

"What? The Qing army was equipped with shells filled with picric acid explosives? Didn't the intelligence department have any information about the equipment of the Qing army? "There has been bad news from Shandong, and Zhao Yi's temper is becoming more and more unstable.

"The formation and training of the new army has always been handled by the New Party, and our high-level inner line of the Qing army is all from the Ronglu line, which is the so-called rear party, and it is not surprising that we have not been able to grasp the equipment and new trends of the Qing army in time." Wang He said.

"Actually, what I'm worried about is not what equipment the new army of the Qing army has updated, anyway, no matter how they change, there is still a generation gap compared to us. However, it was really surprising that the Qing army and the new army learned to be obedient so quickly, and learned the anti-American armed forces without a teacher. Wang He continued.

"Now that I've learned to shell in pieces, will I learn to bury IED again after a while?" Hao Dajian said.

"Let's not talk about the IED, even this kind of low-precision shelling is enough for us to drink a pot." Lu Xiangyang said.

Taking the airfield in Kandahar as an example, when dealing with the attacks of anti-US forces on personnel at airport facilities through mortars and rockets, Lu Xiangyang said that this is nothing more than aerial reconnaissance and strikes, counter-artillery radar and artillery counterattacks, and dispatching patrols to clear up the airfield.

Judging from the situation of the group of rough embryos trapped in Zibo, Shandong, don't think about providing them with air support for a long time; Due to the lack of manpower, it is also unrealistic to send patrols in all directions at the same time, and in the end the only way left is to passively locate the attacker with counter-battery radar.

"It seems that we have to revise the list of airborne supplies to Shandong today, and first transport a 'Weasel 2' 120-mm self-propelled mortar vehicle and a set of 'Arthur B' counter-battery radar," Zhao Yi said.

Zhao Yiyi's thinking was very clear, and his goal was only one, that is, to immediately strangle the embryonic anti-American forces and similar guerrilla tactics used by the Qing army.

Once the hostile forces of this time and space discover that this tactic can still cause considerable losses to the traversers despite the huge gap in the twin equipment, then Pandora's box will be opened for the traversers. Just go through the poor population, where can you stand others doing this!

"A 'Weasel 2' infantry tank is four tons, and we still have to find a vehicle for the 'Arthur B' counter-battery radar, and our 'Osprey' transport plane may have to make two trips to deploy these equipment in place." Chopper said.

"Even if it is divided into ten times, it will have to be lucky, with the main battle tank of more than 60 tons like 'Merkava 4', they don't know how many roads to detour from Zibo back to Yantai. Lu Xiangyang shook the revised map from Yantai to Jinan sent back by the Navy SEALs who had gone to the decapitation mission.

Even today, in the 21 st century, the nearly 70-ton size of the "Merkava-4" main battle tank may not be able to safely pass through all the roads and bridges in Shandong. You must know that the total weight of the Rabbit's Type 99 main battle tank is only between 51 tons and 58 tons. In Shandong at the end of the 19th century, the flying saucer head must not be the fate of the bridge when it sees it?

Finally, the day after being shelled by the new army of the Qing army, Xiong Bo drove the "Osprey" transport plane and flew to Zibo again with a "Weasel 2" self-propelled mortar vehicle and a squad of ground fighters.

The maintenance department plans to install the "Arthur B" counter-battery radar made in Sweden on a "Weasel-2" armored personnel carrier, which will take a little time, and the complete counter-battery system can only be deployed next time.
