Dark of the Moon film
Before the Autobots seperate from the humans during the Battle of Chicago, Que gives some boom sticks along with grapple gloves to the humans for use in battle against the Decepticons. Sam Witwicky takes two for use.

After getting seperated from Robert Epps and his team, Sam Witwicky and Carly Brooks-Spencer come under attack by Starscream. Sam fights Starscream, shooting him in the right optic with his grapple glove, half-blinding him and resulting in Starscream thrashing around and ultimatly flinging Sam through a window. When NEST attacks Starscream, it gives Sam time to grab one of his boom sticks and arm it. Sam then jumps on Starscream's head and stabs the boom stick into his other optic, rendering him totally blind. As Starscream desperatly tries to get rid of the grappling hook and boom stick, Lieutenant Colonel William Lennox works to cut Sam free so he won't be killed when the boom stick goes off. Lennox succeds in cutting Sam free and as Bumblebee catches the two, the boom stick goes off, decaptiating and killing Starscream.

Later, Sam tries to use his second boom stick to attack Soundwave and stop him from killing Bumblebee, but the boom stick shorts out and Sam is unable to use it.
