At just 25, Mwiza is not only part of the Rwanda Defense Force (RDF), she is also currently serving as a helicopter pilot on a United Nations Peacekeeping mission stationed in Juba, South Sudan.

Mwiza says that being sent on her first UN Mission in 2017 was an opportunity to work alongside many other peacekeepers while also getting exposure to many other cultures and ways of life.

While Mwiza is single and has no children, 39-year-old Major Stella Uwineza had to leave her husband of 11 years and three children to serve on UN Mission in South Sudan.

As of 2019, out of approximately 95,000 peacekeepers globally, women constituted 4.7 percent of military contingents and 10.8 percent of formed police units in UN peacekeeping missions.

The first peacekeepers for Rwanda were deployed 15 years ago to what was the then AU Mission in Darfur, Sudan which later became a hybrid force, after UN got involved.
