Being facetious doesn't look very good either. Guy made an unqualified comment and was promptly schooled. Give it a rest already.

He Xianda: From a cook to an "ace operator"

Editor's Note: The delegates to the 20th National Congress of the Communist Party of China (CPC) are outstanding Party members with remarkable achievements. They are selected from and trusted by more than 96 million members and more than 4.9 million grass-roots organizations of the CPC, embodying the pioneering nature of the CPC and carrying the expectations of the Chinese people. China Military Online is publishing a series of stories to elaborate the outstanding deeds of some delegates.
In a training range in South China, a brigade of the PLA Rocket Force (PLARF) was conducting a missile launch drill. Along with the order issued, several operators immediately rushed to the missile launcher. After sophisticated operations of the launcher, they successfully hit the simulated target.
Upon the completion of the drill, He Xianda, Master Sergeant, Class-I from the 1st missile launching battalion of the brigade, who is also a delegate to the 20th National Congress of the Communist Party of China (CPC), immediately organized evaluation and summary of the exercise to find out the weaknesses in command planning and weapon operation and came up with measures for further improvement.
He Xianda, a first-class operator and first-class commander of missile launcher of the brigade, is proficient in operation skills for more than 10 posts and has got involved in the compilation of more than 20 professional textbooks and more than 40 operating instructions.
It is hard to believe that He started his service in the PLA as a cook. Like the other PLARF soldiers, He also dreamed of sending missiles to the sky with his own hand. However, He was assigned to the cooking squad of a company after finishing recruits' training.
Yet, He Xianda didn't give up his dream. He managed to do a good job in the cooking squad while studying knowledge and skills required for operating missiles. Half a year later, in a military skills competition that involves the entire brigade, He stood out with excellent performance and was thus appointed as an operator responsible for missile transshipment.
Since growing into a master in missile transshipment, He Xianda took the initiative to take lessons in missile launching and has become the first noncommissioned officer in the brigade to act as the "leading operator" in the missile launcher.
Several years ago, the brigade ushered in a live-fire training exercise, and the missile to be launched in the exercise was the 100th missile the brigade had ever launched. Except for He Xianda, it was the first time for the other operators assigned to the mission to launch a real missile, including 3 rookies.
He led the other operators to go through arduous training of required skills, and they all got the "admission ticket" for the 100th missile launch task as scheduled.
On the very day of the live-fire training exercise, as He Xianda issued the order of "fire" on time, the missile was blasted into the sky and precisely hit the target. The success of the launch not only announced the birth of one more combat unit with live launch experience, but also marked the commencement of missile launching for the PLARF under extreme temperature conditions.
Over the past years, the squad with He Xianda as the squad leader has triumphed in 22 military skill competitions and won the first place in the brigade's 10 missile launching assessments.

"Target is heading toward us while hedgehopping above the sea. It's approaching the limit for attack…" During a multi-service confrontational exercise conducted by the PLA Hong Kong Garrison troops at midnight of a summer day, an incoming "enemy plane" was captured by radar.
"Three missiles, fire in sequence!" Following the order given by Wang Haixu, commander of an air defense battalion in a regiment of the PLA HK Garrison, the missiles hit the target precisely.
Wang Haixu is also a deputy to the 20th CPC National Congress.
Eighteen years ago, when Wang was still in college, he was inspired by the recruitment posters and suspended his study to join the PLA. Later he joined the CPC during service and passed the military academy entrance examinations organized by the military for soldiers in active service and was admitted by the Air Force Engineering University.
When serving at a ground-to-air missile brigade of the PLA Air Force, he participated in a number of major training exercises, and was promoted from platoon leader to deputy company commander and then to company commander. At the end of 2019, he was appointed head of the air defense battalion in a regiment of the PLA HK Garrison after rounds of selections and assessments.
"As a battalion commander, it is my duty to lead the whole unit to become more competent at fulfilling tasks and make sure whenever we are called upon, we'd be able to act quickly, shoot precisely, and safeguard HK's air defense security," said Wang.
In the autumn of 2020, when leading the battalion to carry out an exercise in a sea area, Wang and his men came cross a headache -- the radar screen was full of snowflakes under the influence of sea clutter.
As Hong Kong is surrounded by sea on three sides, the air defense radar would easily lose target under the influence of strong sea clutter."Searching and identifying the target was like looking for a needle in a haystack," said the radar technician Zhang Yanrui. Wang led several technical backbones to form a research team to tackle the problem. They collected data, analyzed waveforms, and study the patterns at the seaside position every day.
Having compared and analyzed thousands of data sets, they began to discern patterns in the originally chaotic radar noise map, and the effects exerted by sea clutter on the gun-projectile system were removed one by one. During the simulated ground-to-air confrontation drill, Wang and his men accurately identified the air targets in their defense area, and got the highest score of all 9 participating units.
Over the years, Wang Haixu has taken the lead in making innovations of operational tactics and made 76 inventions. Three new tactics, including the air defense tactics against sea clutter in coastal areas, were conferred the innovation awards by the superior. Since stationed in HK three years ago, Wang has led the air defense battalion to participate in live-fire exercises multiple times with all their missiles hitting the target, breaking the live-fire shooting record of a certain type of weapon system. He has personally been honored with a second-class merit citation and a third-class merit citation, and his battalion a third-class collective merit citation.
"To achieve the centenary objectives of the PLA, I will earnestly fulfill my duties as a deputy to the 20th CPC National Congress, dedicate myself to the military training and war preparedness, and perform well the defense mission in Hong Kong entrusted by the Party and the people," said Wang.

Surprise to see that type15 turrent do not have anti skid surface.

General
A novel way of mitigating unwanted vibrations during CNC machining process, invented by a CNC machine operator who makes precision parts for armor vehicles.
First, some background information. Prior to machining, a metal blank must be secured carefully so that the impact of CNC drills doesn't cause unwanted vibrations and displacement that could result in the finished part being off-spec. Traditionally, the blank is secured to a complicated fixture that must be laboriously calibrated and re-adjusted periodically (1st image).
A new method of using frost to secure the blanks has been developed that greatly simplifies the process. The idea came to the inventor one day when he was cleaning out his refrigerator and was having great difficulty trying to remove a piece of grocery stuck to the fridge walls by a layer of frost.
After some tinkering, he invented a special mounting platform that can be chilled to below freezing. First, some water is sprayed onto the special platform (2nd image), and a blank is placed onto the platform. The platform is then chilled to below freezing, which produces a layer of frost that very securely binds the blank to the platform (4th and 5th image), with the binding strong enough to withstand the forces and vibrations from CNC drills.
