Russian Border troops green 100% wool beret with Soviet soldier metal badge.

Green Berets - Russian Ground Forces, Internal Troops Intelligence (will often wear headwear of other units in the field to avoid identification), Border Guard Service of Russia Special Forces and Russian Railway Troops. 

Berets have been implemented on a smaller scale as parade headgear for troops who parade in field uniforms.

Units that currently wear the beret are the paratroopers, marines (naval infantry), troops of the MVD special forces, and Ministry for Emergency Situations, and certain special forces units of the GRU and other branches of the armed forces. 

All other units wear the visor cap on parade and the field cap in the field and on exercise. As of the former 2011 regulations, each branch had a colour for their beret.
