We present results from the "Mint" resolution DC Justice League suite ofMilky Way-like zoom-in cosmological simulations, which extend our study ofnearby galaxies down into the ultra-faint dwarf (UFD) regime for the firsttime. The mass resolution of these simulations is the highest ever publishedfor cosmological Milky Way zoom-in simulations run to $z=0$, with initial star(dark matter) particle masses of 994 (17900) M$_\odot$, and a force resolutionof 87 pc. We study the surrounding dwarfs and UFDs, and find the simulationsmatch the observed dynamical properties of galaxies with $-3 < M_V < -19$, andreproduce the scatter seen in the size-luminosity plane for $r_h\gtrsim200$ pc.We predict the vast majority of nearby galaxies will be observable by the VeraRubin Observatory's co-added Legacy Survey of Space and Time (LSST). Weadditionally show that faint dwarfs with velocity dispersions $\lesssim5$ km/sresult from severe tidal stripping of the host halo. We investigate thequenching of UFDs in a hydrodynamical Milky Way context, and find that themajority of UFDs are quenched prior to interactions with the Milky Way, thoughsome of the quenched UFDs retain their gas until infall. Additionally thesesimulations yield some unique dwarfs that are the first of their kind to besimulated, e.g., an HI-rich field UFD, a late-forming UFD that has structuralproperties similar to Crater 2, as well as a compact dwarf satellite that hasno dark matter at $z=0$.
