A front thrust is a front kick designed for power, and done with the rear leg. It is chambered and driven through the target (torso) with a high degree of force, and returned immediately to the starting position or placed forward to step through. The striking surface is the heel or the whole sole. This is often the kick used to break down doors on television. It was famously used in the movie 300 when Leonidas yelled, "This is Sparta!" and kicked the messenger into the pit.
