For Leibel Mangel - being the son of a Chabad Rabbi and the grandson of one of the youngest survivors of Auschwitz - serving in the IDF was not a matter of if, but rather when. Leibel, at the age of 19, left his home in Cincinnati, to enlist in the IDF. He served as a machine gunner in the Kfir Brigade, where he took part in numerous high profile anti-terror operations.

Even after his military discharge, Leibel has continued his service by fighting for Israel and the Jewish people in both the mainstream and social media, in cities and college campuses throughout the USA. Leibel is a 2017 Jewish People's Choice Award winner. 

Leibel is also a Krav Maga instructor - helping civilians defend themselves with IDF hand to hand combat.
