We study the superfluid response and localization dynamics from static andmobile impurities. The superfluidity is formed in the rung-Mott phase of abosonic ladder model producing spin-Meissner currents induced by a$\mathbb{U}(1)$ gauge field or a uniform magnetic field. Impurities aredescribed through two-state systems which act as a two-peak random potential.An impurity sits either at the top or at the bottom of the ladder on each rungequally, producing a telegraph signal. The impurities-matter coupling givesrise to a classical Ising symmetry for static and mobile impurities associatedto the inversion symmetry of the two legs of the ladder. From the decoupledrungs limit, we also identify a local $\mathbb{Z}_2$ gauge theory for mobileimpurities. The properties of the system are studied from an effective quantumspin model including the possibility of four-body coupling in the limit of astrong interaction between bosons and impurities. Through analytical approachesand numerical exact diagonalization, we study the superfluid currents both inthe weakly-coupled and strongly-coupled rungs limits for the bosons. In theweakly-coupled rungs situation, we find a smooth power-law localization whereasthe strongly-coupled rungs limit produces a steep localization or insulatingphase for various configurations of the two-peak random potential. In thestrongly disordered situation, through entanglement and bipartite fluctuationmeasures, we also identify a many-body localization regime in time after aquench of the system when prepared in a N\' eel state.
