The African missions today need peace enforcement in many cases, as in South Sudan, in DRC and in the Central African Republic. That requires combat-capable troops. Peace enforcement is only done when all other means have failed. As a last resort you use peacekeepers to do combat.
In many of these countries, it's absolutely necessary. The locals are pleading for peacekeepers to do something. They see them in their armoured personnel carriers moving around but not taking on the gangs. It's very important that the UN be more robust and provide a robust capability.
Canada can provide training. Some African peacekeeping training centres are using a simulation that I developed, a video game. You don't play a war fighter; you play a peacekeeper. The UN is considering adopting that.
