What is the origin of the polar bear regiment annihilated by volunteers on the battlefield to resist US aggression and aid Korea?

In October, 195, in the Xinxingli battlefield in Changjin Lake, North Korea, the volunteer soldiers who had finished fighting were cleaning up, and the cooking squad was ready to cook, but the cage cloth for steaming steamed bread was gone, so the squad leader Zhang Jiqing casually pulled out a fancy cloth from the spoils and handed it to the cook to wash and use as the cage cloth. At this time, the translator Liu Guangrui grabbed the cloth and said, "This is the flag of the American polar bear regiment." When this was said, the soldiers also gathered around. Liu Guangrui pushed the crowd away and sent the flag to the battalion commander Bi Xuyang, who sent it to the regimental headquarters. To this end, the polar bear regiment was confirmed to have been wiped out, and the 4 th company of the 239 th regiment was awarded the banner of "Xinxing Li Combat Model Company" by the 27 th Army.

So, what exactly is this wiped out polar bear regiment? What are their achievements?

The Polar Bear Regiment, formerly known as the 31st Regiment of the 7th Infantry Division of the US Army, is one of the most elite troops in the history of the US military. The most brilliant achievement was that during World War I, the 31st Regiment successfully attacked and entered the Siberian region of Russia. In recognition of their achievements, US President Woodrow Wilson awarded 31 regiments the title of "Polar Bear Regiment" and personally awarded the "Polar Bear Flag", which is the flag that our soldiers will use as the cage cloth for steaming steamed bread.

On December 1st, 195, the once-swaggering "polar bear regiment" was no longer down in prestige. It was annihilated by the organizational system under the strong offensive of Chinese people's Volunteer Army, and completely prostrated at the feet of the volunteers, and could no longer stand up.

At that time, the commander of the polar bear regiment was Lieutenant Colonel Faith. Lieutenant Colonel Faith retreated with the defeated United Nations troops, and was intercepted by the 1st Battalion of the 242nd Regiment of the Volunteers, and was finally killed.
