The four horsemen of Revelation 6 are: 

1.    The white horse whose rider is Antichrist (vs.2), counterfeits the return of Christ and produces a fraudulent peace pact (Revelation 19:11). 

2.     The red horse (vs. 4) produces wars and rumors of wars.  Perhaps Russia (red) might have a part here. 

3.     The black horse (vs. 5) produces famine and inflation as the 666 program becomes activated. 

4.     The pale horse (vs. 8), the deadliest, produces death and disease with hell following him. 

Countless horses will be utilized by the armies of Armageddon as the blood rises to their bridles (Revelation 14:20), and Christ himself will return, mounted on a white horse, followed by His armies also riding white horses (Revelation 19:11-14).
