Hydrodynamically, if the host halo contains thermalized hot gas, this can strip and heat the extended gas from the orbiting satellite subhalo \citep{Balogh2000, McCarthy2008}, leading to reduced gas cooling/accretion into the satellite's disk \citep{Larson1980}.  More drastically, given a sufficiently high density of hot gas and high orbital velocity, ram-pressure can strip cold gas directly from the satellite's disk \citep{GunnGott1972, Abadi1999, Mayer2006, Chung2009, Tonnesen2009}.  Furthermore, feedback from stars and/or AGN within the satellites can drive galactic winds that can enable these environmental process to operate even more efficiently \citep[for example,][]{BaheMcCarthy2015}.  In this letter, we examine the environmental quenching timescales of the current satellite galaxies in the LG, considering the possible impact of group preprocessing.
