Shoot out the wires

You decide to shoot the wires providing power to the compound from the solar panels. This turns out to be a lot easier in theory than in practice. There are six buildings in the compound, each providing power to the perimeter systems via a thick cable. Each cable takes one or two shots to sever, and despite liberal use of the laser pointer, you still miss quite a bit. Getting the little red dot to stay on target while you squeeze the trigger seems to be the hardest part--not something that would be a problem if you were shooting at an attacker, maybe, but shooting at a wire is different.

It takes you a couple hours of persistent effort and about half of your ammunition, but eventually the last cable is blasted apart. The lock on the gate clicks and it slowly swings open as the hydraulics fail in the "open" position. You can now just walk right inside.
