US - Excalibur Guided Round

The Excalibur is a GPS guided round that can be fired from a number of artillery platforms including the M109 Paladin. With a Circular Error Probability of a mere 32.8 ft, the Excalibur offers extreme accuracy.

The Excalibur projectile is a true precision weapon, impacting at a radial miss distance of less than two meters from the target. Unlike “near precision” guidance systems, the Excalibur weapon provides accurate first-round effects at all ranges in all weather conditions. This weapon system also extends the reach of .39-caliber artillery to 40 km and .52-caliber artillery to more than 50 km.

By using the Excalibur projectile's level of precision, there is a dramatic reduction in the time, cost and logistical burden associated with other artillery munitions. Analyses have shown that on average, it can take at least 10 conventional munitions to accomplish what one Excalibur weapon can.

The Excalibur munition is compatible with every howitzer with which it’s been tested. This weapon is fully qualified in multiple systems, including the M777, M109 series, M198, the Archer and PzH2000. It’s also compatible with the AS90, K9 and G6 howitzers. Plans are underway to integrate it with other mobile artillery systems.
The Excalibur projectile’s precision, coupled with its ability to be integrated on multiple gun systems, enables both the U.S. and its coalition partners to provide overmatch capabilities against land targets in a variety of combat environments. This includes stationary land targets.

The 2K25 Krasnopol^[ is a Soviet 152/155 mm cannon-launched, fin-stabilized, base bleed-assisted, semi-automatic laser-guided, artillery weapon system. It automatically 'homes' on a point illuminated by a laser designator, typically operated by a ground-based artillery observer.

 Krasnopol projectiles are fired mainly from Soviet self-propelled howitzers such as the 2S3 Akatsiya and 2S19 Msta-S and intended to engage small ground targets such as tanks, other direct fire weapons, strong-points, or other significant point targets visible to the observer. 

It can be used against both stationary and moving targets (providing these remain within the observer's field of view).
