Humanitarian agencies regularly cite government troops as the largest single group of perpetrators of widespread sexual violence in the Kivu region, says our reporter, who is in the town of Baraka, not far from Fizi.
Sitting in a mobile court in Baraka, the military judges also sentenced three officers serving under Lt Col Kibibi to 20 years and five soldiers to between 10 and 15 years.
Lt Col Kibibi Mutware is one of many former rebels who joined the army as part of peace agreements in 2009.
More than 60 women were raped on 1 January in Fizi.

“I was fleeing the violence but unfortunately I met four soldiers, ” a 29-year-old mother of five told the BBC about the events on New Year’s day.

In August 2010, rebel forces were accused of raping hundreds of women, girls, men and boys around the town of Luvungi.
The UN recorded some 11,000 rapes in 2010 - the true figure is believed to be much higher.
Our reporter says since January there have been other reports of sexual violence in an area where the Rwandan FDLR rebels are still active, 40km (about 25 miles) from Fizi.
Medical charity Medecins Sans Frontieres says it is planning to deploy a mobile clinic to the area on Monday after receiving credible reports of 30 new rapes last week.
It says it has treated more than 70 victims of rapes in two similar incidents in the area between 19 January and 4 February.
There’s a little bit of justice left in this world.
