Yamagakure Barrier Team

The Yamagakure Barrier Team is a specialized team of jōnin whom are put in charge of protecting the village with various barrier techniques.

Divisions
The team consists of two divisions;

The, consisting of eight shinobi, is responsible for activating and maintaining the barrier. They are posted in the four cardinal directions, in large towers at the edge of the village. At predetermined intervals of time, the current four shinobi operating the barrier are relieved by their comrades, allowing the barrier to remain strong.

The is a team of twelve shinobi tasked with protecting the "enclosing wall division" with their own barrier ninjutsu. In the event that anyone in the main division is wounded or killed, each member of this division is also aware of the barrier ninjutsu used to protect the village, and can act as stand-ins.

Barrier
The barrier this team is responsible for is a barrier of its own creation; the Four Divine Beasts Barrier. The spherical barrier is invisible to most, save those who have unique dōjutsu, such as the Sharingan or Rinnegan. The barrier is, for all intents and purposes, impenetrable. According to the First Yamakage, it would take a destructive force of almost twice the power of a Tailed Beast Ball to do damage to the barrier. By pouring their chakra inside this barrier, the users can repair any damage done to it rather quickly.
