Abstract Scope	Understanding the strength of metals has been a scientific challenge for many decades. Much progress has recently been made toward understanding the plastic strength of metals, thanks to the method of discrete dislocation dynamics (DDD). This method is limited to probing the deformation behavior of metals in the small strain range. Continuum dislocation dynamics (CDD) is capable of extending simulations to larger strains keeping the same physics. CDD casts dislocations dynamics in the form of transport-reaction equations for dislocations after expressing them as density fields. Coupled with crystal mechanics, these equations provide the plastic constitutive part required solve the crystal deformation problem self-consistently. Closing these equations requires modelling of the spatial, line-direction, and temporal statistics of large dislocation systems and their internal stress. We will review the recent progress in CDD development, with emphasis on its statistical underpinning: internal stress fluctuations, dislocation correlations, and line-direction statistics.
