The SMArt 155 is a German 155 mm artillery round designed for a long-range, indirect fire top-attack role against armoured vehicles. The projectile was developed in 1989 by Diehl BGT Defence in Überlingen, Germany, with Rheinmetall and started full-rate production for the German Army in 1998. It consists of a 47-kilogram (104 lb) heavy artillery projectile containing two autonomous, sensor-fused, "fire-and-forget" submunitions. Due to the submunitions, it has been considered by some to be a cluster munition. As of 2008, representatives of the German defense ministry have referred to it as not being classified as submunition weapons, which were prohibited by the 2008 Convention on Cluster Munitions.

The M712 Copperhead is a 155 mm caliber cannon-launched guided projectile. It is a fin-stabilized, terminally laser guided, explosive shell intended to engage hard point targets such as tanks, self-propelled howitzers or other high-value targets. It may be fired from different artillery pieces, such as the M114, M109, M198, M777 and CAESAR howitzers. The projectile has a minimum range of 3 km (1.9 mi) and a maximum range of 16 km (9.9 mi).
