Which of the following is included in ground techniques?

The option identified as correct, the trap and roll, is an important ground technique used in various martial arts and self-defense systems. This technique allows an individual to escape from a position of disadvantage, especially when being mounted or held down by an opponent. The trap and roll involves using one’s body weight and leverage to roll the opponent off, creating space to either get back to a standing position or to gain a more advantageous position on the ground.

Ground techniques are characterized by the methods used when grappling on the mat or the floor, where balance and weight distribution play crucial roles. While joint locks, simple takedowns, and arm drags are all techniques that can be utilized in grappling, they focus more on controlling the opponent or bringing them to the ground rather than specifically addressing situations where one is already on the ground and needs to escape or reverse the situation. The trap and roll is uniquely suited to this scenario.
