What were the flamethrowers trying to accomplish?

Flamethrowers were primarily designed for military use, aiming to clear enemy trenches, bunkers, and fortifications by projecting a stream of fire. They were also employed to create psychological terror, demoralizing enemy troops and forcing them to abandon their positions. Additionally, flamethrowers could be used in other contexts, such as clearing vegetation or controlling wildfires. Overall, their primary goal was to enhance combat effectiveness through destruction and intimidation.
