Led by their skillful staff sergeant (Aaron Eckhart), a platoon of gutsy Marines, including Santos (Michelle Rodriguez), Simmons (Taylor Handley) and Lockett (Cory Hardrict), fight to protect all humankind from astonishingly powerful aliens who've suddenly invaded Los Angeles. Jonathan Liebesman (The Texas Chainsaw Massacre: The Beginning) directs this sci-fi film that also stars Lucas Till, Ramon Rodriguez, Bridget Moynahan and Michael Peña.
This is a Northrop Grumman Laser Systems AN/PEQ-1A Special Operations Forces Laser Acquistion Marker (SOFLAM) based prop, the prop laser designator used by Aaron Eckhart as "Sgt. Michael Nantz" and can be seen near the end of the film as he uses it to target the large alien spacecraft.
The prop is made of wood, metal and plastic and the back side features lots of switches and a fake viewfinder. It is connected by a power cord to a canvas bag that contains foam simulating the batteries required to operate the unit on field. It actually holds the bag's shape as CGI was used for the laser beam on postproduction.
The laser designator has some heavy wear from use and despite lots of dirt and dust due to the kind of set the movie is shot, it features several scratches and dings that easily match on close up shots on screen. This is one of the key props used in the film.
