Jennifer Lopez -- It Takes an Army ... To Walk 30 Feet

Jennifer Lopez takes her security very seriously ... because today in New York, she strolled all of 30 feet flanked by a TEAM of security that acted like it was escorting the president.

JLo was leaving an office building Thursday afternoon when our photog tried to ask her about the anti-paparazzi clause in her divorce settlement with Marc Anthony.

But her team -- at least 3 bodyguards and 2 handlers -- had ALL sides (even that one) covered ... making it clear NO ONE gets close to JLo.
