Selectable Lightweight Attack Munition or (M2/M3/M4 SLAM) is a small multi-purpose landmine produced by ATK Precision Fuze Company in Janesville, Wisconsin from 1992-2002. It has a passive infrared sensor and a magnetic influence sensor which allows it to be used as a demolition munition, off-route mine or full-width belly attack mine. The SLAM is compact and weighs only 1 kilogram, so it is easily man-portable. The SLAM is intended for use against APCs, parked aircraft, wheeled or tracked vehicles, stationary targets (such as electrical transformers), small fuel-storage tanks (less than 38,000 liters (10,000 US gal)), and ammunition storage facilities. When the mine is triggered, the Misznay-Schardin effect generates a copper explosively formed penetrator (EFP), which can penetrate 40 millimeters of armor at a range of eight meters. The SLAM has an anti-tamper feature that is only active in the bottom- and side-attack modes. The SLAM will detonate when an attempt is made to change the selector switch's position after arming. The M4 is normally used by units designated as light, airborne, air assault, crisis response, and rapid deployment.

The SLAM is produced in three versions:
* M2 - Solid green, with no labels, which silently self-neutralizes at the end of its active period (either 4, 10 or 24 hours)
* M3 - Can only be used in the command-detonated mode.
* M4 - Green with a black painted warhead face, which self-destructs at the end of its active period (either 4, 10 or 24 hours).
