CDS and CJNG remain top players. Zetas and CDG still hold territories taken back in 2010/11 but they don't seem to have made gains. BLO is almost gone with the major hits they've taken the last couple year (death of H2, H9, arrest of el Tortillero and el Guero Saba). La Linea for sure have cornered CDS to the South-western part of Chihuaha, they have started to enter Sonora. CDN has not grown as a cartel they only hold Nuevo Laredo and Nuevo Leon and they seem to have lost Ciudad Victoria Tamaulipas (their other stronghold) to Zetas.
