Sand Mounds

The most basic defense on mars are substanstial piles of martian sand around the Homestead or Settlement. These large mounds help to break up the line of attack as an attacker approaches the installation, as well as driving them into certain points of access due to the difficulty of scaling martian sand at any significant speed.

Due to being a completely passive defense, and completely unpowered or adjustable in any way after installation, most of those concerned with home defense quickly look to upgrade to the more versitile Barb Wire.
