Caltrop field/Legends

A Caltrop Field was a field of large spikes in the ground.

In Star Wars: The Clone Wars (TV series), in the episode Landing at Point Rain, Jedi Master Ki-Adi-Mundi was forced to use his lightsaber to cut through several Geonosian caltrops to allow his one surviving AT-TE to proceed to the landing zone where the three Generals commanding the attack were to rendevous.
