I want to know the answer to the following question:
Soldiers from which country were brought to the Congo?
All the background I'm provided with is that "Massamba-Débat's regime also invited several hundred Cuban army troops into the country to train his party's militia units and these troops helped his government survive a coup in 1966 led by paratroopers loyal to future President Marien Ngouabi.". Is that enough to answer the question?
Answer: yes
