Dangers in "The Hurt Locker," for short

IEDS

These explosive devices are often hidden along roadsides and triggered remotely or by pressure, posing a major threat in modern warfare. The acronym stands for their improvised nature.

This clue refers to the deadly explosive devices featured in The Hurt Locker, the 2008 war film about bomb disposal teams in Iraq. "For short" signals that the answer is an abbreviation—IEDs stand for "improvised explosive devices," a common threat in the movie. The plural "dangers" hints at the S at the end of the answer.
