How many mistakes does "Bright Sword" have?

Hello, Liang Jian has several mistakes:

(1) In the first episode, in order to go back and save Zhang Dabiao who was trapped in the breakout, Li Yunlong said, "Since the establishment of our independent group, none of our brothers have fallen." At this time, the troops he commanded were a new regiment of the 386 Brigade.

(2) After Chu Yun Fei was injured, the officer said, "The bullet that hit you was a Thomson submachine gun, you know …" It was actually a M3 submachine gun that hit Chu Yun Fei, nicknamed the oil gun. A small number of American troops were equipped during World War II.

(3) Zhang Dabiao once said that Thomson submachine gun fire is fierce and light. In fact, the quality of thompson submachine gun is particularly large, which is one kilogram heavier than the 38 rifle. It can be seen that the staff confused M3 with Thomson.

(4) One night, Mu Yi Yamamoto led a small group of devils to sneak attack the headquarters of the Eighth Route Army in Daxiawan. When they passed by Yangcun and tried to sneak around, a microphone appeared at the top of the picture.

(5) When Li Yunlong led the independent regiment to break through the anti-mopping-up, several soldiers had photographic equipment projected.

(6) The independent regiment cavalry company fought fiercely with the Japanese army, and finally only the company commander Sun Desheng was left. When he was ready to attack again, a microphone appeared at the top of the picture.

(7) In the Huai Hai Campaign, in the episode that a company robbed the enemy's goods in Li Yunlong, the teacher of the soldier who robbed the spoils of the People's Liberation Army typed the following introduction as Li Su, but Li Yunlong called him Lao Zhang.

I hope I can help you! thank you
