US army to provide equipment, intelligence to fight Boko Haram

The United States military will provide communications equipment and intelligence to help African nations in the fight against Nigerian Islamist group Boko Haram, the commander of U.S. Special Forces operations in Africa said.

West African military commanders have long complained that cross-border operations against Islamist groups, from al Qaeda in the Islamic Maghreb (AQIM) in Mali to Boko Haram in Nigeria, have been obstructed by lack of compatible communications equipment, making it hard to swap information and coordinate.

Brigadier General James Linder said that, as part of the annual U.S.-backed 'Flintlock' counter-terrorism exercises this year in Chad, the United States would provide technology allowing African partners to communicate between cellphones, radios and computers.

The system also incorporates a translation function that would allow commanders in francophone countries like Chad to communicate by message with English-speaking officers in Nigeria, a U.S. military officer said.

Boko Haram killed an estimated 10,000 people last year in its campaign to carve an Islamist emirate from northern Nigeria. Amid growing international alarm, the four nations of the Lake Chad region -- Chad, Niger, Cameroon and Nigeria -- plus neighbouring Benin are preparing a joint task-force of 8,700 men to take on the Sunni jihadist group.

Chad's military, which played a leading role in a French-led campaign that ousted Islamist groups from northern Mali in 2013, has already led attacks against Boko Haram positions in Nigeria's border regions.

"The Lake Chad nations are battling Boko Haram and we have a vested interest in that group of nations' collective success ... What Boko Harm is doing is a murderous rampage, about brutality intolerance and subjugation," Linder said in an interview late on Monday.

"Our national leadership has been very clear that more was going to be done ... There is an ongoing discussion on how will we provide additional tools, techniques, and material to partner nations."

At the Flintlock exercises, the U.S. military will also be introducing a Cloud-based technology to allows African allies to quickly share intelligence across borders, such as mapping information the location of potential targets, Linder said.

The ninth edition of Flintlock, grouping 1,300 soldiers from 28 African and Western nations, will emphasise the importance of troops fostering strong relations with local communities to gain intelligence on insurgent groups.

Linder said that African armies were well placed to gather this kind of information, but the United States could share other kinds of intelligence to boost the success of operations against Boko Haram.

"It's the things that we find from flying over a target and having an FMV, a full motion video, or being able to take pictures, or being able to do a different type of geo-spatial analysis or predictive analysis on the enemy," he said.

Washington's long-term goal was to enable African nations to be sufficiently trained and equipped to face their own security challenges, Linder said.

"By 2050, one-third of the global population will be on the African continent," he said. "The global economy and the global community need stable countries in Africa and that can only happen through African nation states themselves."
