Mitzvah tank

A Mitzvah tank is a vehicle used by the Orthodox Jewish practitioners of Chabad-Lubavitch Hasidism as a portable "educational and outreach center" and "mini-synagogue" (or "minagogue") to reach out to non-observant and alienated Jews.

Lubavitchers use these vehicles to spread the teachings of Judaism to the Jewish masses in "military fashion" in which "campaigns" and battles are fought, hence naming the vans and trucks "tanks".

[3] The strategy behind the Mitzvah tank "campaigns" was designed and encouraged by the seventh rebbe of Chabad Lubavitch, Rabbi Menachem Mendel Schneerson .

The vehicles often have large banners or logos on them, extolling some aspect of Judaism or displaying images of Rabbi Schneerson and about Moshiach's imminent arrival.

[6] The tanks, usually manned by young male Lubavitch students in the Yeshiva of Tomchei Temimim, park in areas with heavy people-traffic and seek Jews to perform Mitzvahs by asking passers-by: "Are you Jewish?"
