This puts the lie to the above comment, and the Slashdot article that implies that they only shot a liquid-fueled target because it was easier. Furthermore, the solid-fueled target was identical to one that the ALTB had destroyed in flight a week earlier.

Less than one hour later, a second solid fuel short-range missile was launched from a ground location on San Nicolas Island, Calif. and the ALTB successfully engaged the boosting target with its High Energy Laser, met all its test criteria, and terminated lasing prior to destroying the second target. The ALTB destroyed a solid fuel missile, identical to the second target, in flight on February 3, 2010.

Companies have been making exoskeletons ever since the "Hardiman" of the 1960s.

Of course they did not show that part in the movie.
