We are also a powerful military country. Why is the Russian army so powerful in Syria, but the US military is being chased by the Taliban?

This is mainly due to the different geographical characteristics of Syria and Afghanistan. Syria is all plains, so the Russian army basically focuses on urban combat. Can launch large-scale swarm operations. However, Afghanistan is more mountainous. It is not conducive to large-scale cluster operations, and the Taliban are very good at guerrilla tactics. It makes the US military unable to defend itself, which is why the current situation is caused.

First of all, Russia has invested a large number of troops and advanced equipment in Syria. Not only that, Russia also controls the air over Syria. Syrian opposition positions can be bombed at any time. Moreover, because Syria is a country in the plains, Russia's fast mobile troops can quickly eliminate the Syrian opposition forces. Not only that, the Syrian opposition armed forces are all a ragtag group of people with very low training levels. Of course, they cannot be compared with regular troops like Russia. Therefore, it is normal for the Russian army to be unstoppable in Syria.

However, Afghanistan, where the Taliban is located, is a mountainous country. This first makes it impossible to launch large-scale armored cluster operations. It was more of a security war, although the United States eliminated the Taliban armed regime within a few hours. But it got stuck in a long tug-of-war. Over the next 10 years or so, the Taliban launched a guerrilla war by taking advantage of the mountainous terrain. This made the US military unable to defend itself and fell into the whirlpool of war. Moreover, the Taliban armed forces have been adapted from some regularized units. Therefore, it is also very powerful in terms of combat effectiveness.

So they are both powerful military powers, but the opponents and geographical conditions they faced in these two wars were different, so they cannot be directly compared. Moreover, the armies of these two countries have undergone a large number of actual combat drills, so the quality of their soldiers is very strong.
