Why aren't flamethrowers used anymore?

Flamethrowers are not commonly used in modern warfare due to their limited range, vulnerability in combat, and the potential for causing indiscriminate harm to civilians and the environment. Advances in military technology have led to more effective and precise weapons that accomplish similar objectives without the risks associated with flamethrowers. Additionally, international laws and conventions have increasingly restricted their use due to humanitarian concerns. As a result, they have largely fallen out of favor in contemporary military strategies.
