The doctrine is carried out through the shluchim, emissary couples sent by Chabad, often married and with young children, to serve Jewish communities anywhere in the world with little or no existing local infrastructure, from major cities to small towns with only a handful of Jewish residents. The Rebbe's Army describes the movement's public mitzvah campaigns, roadside stands offering passersby the chance to put on tefillin, public menorah lightings in city squares each Hanukkah, distribution of Shabbat candles before the holiday begins, as deliberately aimed at any Jew encountered rather than restricted to synagogue members, matching the doctrine's own refusal to make engagement conditional on prior observance. The Encyclopaedia Judaica records that this outward structure continued expanding after Schneerson's death in 1994 without a successor Rebbe being appointed, run instead by a lay executive committee overseeing the network of emissaries directly, so that the outreach mission Schneerson set in motion has continued to operate at global scale under an institutional structure built to outlast any single leader's own tenure. Agudas Chasidei Chabad, the umbrella body coordinating the network, absorbed the practical decisions a living Rebbe had once made personally, a transition the movement completed without slowing the rate at which new emissary postings continued to open around the world.
