It seems that these days commandos has an impression of shorts.
A second partial clone of CSF (but with... solo attitude) is Death to
Spies.

"Looking a bit like Commandos, developed by an unknown Russian studio and
offering a mediocore portion of fun (6.1 at Gamespot). That's action game
Death to Spies, released few moments ago by group RELOADED. There was
quite
popular demoversion of this game so many of you might already played it
and
you can try the full version now.
Smersh is the Russian for "Death to Spies" and was the name of a set of
counterintelligence departments in the Soviet Army formed during World War
II. Their mission was to secure the rear of the active Red Army by
arresting
traitors, deserters, spies and criminal elements. During the war these
agents became the main force combating the German intelligence service.
The game's main character is a captain in the 4th department of the Soviet
counterintelligence service. He is a professional spy trained to execute
dangerous operations on his own. During missions he will have to complete
various tasks in the heart of enemy territory including stealing important
documents, eliminating different enemy officers or high-ranking officials,
kidnapping and sabotage.
Game missions are based on real historical events and operations which
were
executed by the military intelligence and counterintelligence during the
war."
