Yamas (Israel Border Police unit)

Yamas (Hebrew: יחידת המסתערבים, romanized: Yehidat HaMista'arvim, lit. 'the Mista’arvim Unit') is a tactical special unit of the Israeli Border Police. It conducts covert and special operations, counter-terrorism, irregular warfare, and high-risk arrest and search warrants.

It specializes in counterterrorism and provides operational assistance to the Israeli Security Agency (Shin Bet). The unit works in coordination with the Shin Bet and Israel Defense Forces. Members of this unit are primarily drawn from the Israeli police, but its operational command falls under the Israeli army.

It uses Arab disguises to infiltrate and conduct missions in Arab territories. It is considered a covert unit, known for its clandestine operations involving infiltration of Palestinian territory through disguises and civilian infiltration within occupied Arab areas. Its personnel do not wear uniforms and are not permitted to disclose their affiliation with the organization. Its primary mission is dealing with unrest and Arab demonstrations, and it also assists in special and complex arrest operations inside the Green Line.

The unit's sniper teams have won numerous awards and are considered among the best in Israel.
