for the military and techo geeks within, here’s how to disappear.

AS A special-forces agent in the French Navy, Michel Malalo has clandestinely entered several African countries by sea to extract endangered French nationals. Almost all the enemy fighters he encountered carried the AK-47, a widely used assault rifle renowned for its rugged reliability. But the AK-47 has a serious drawback: glint, which gave Mr Malalo an advantage in firefights. Made with steel, the AK-47 reflects light. “It’s flashy—and from afar,” says Mr Malalo, who took advantage of glint giveaways when shooting at the enemy. Mr Malalo, who left the special forces uninjured six years ago, says the French assault rifle, the Famas, is superbly non-reflective even in bright light.
