As the United States military remains wedded to 155mm artillery, Russia’s military is employing heavier fires that, when combined with additional fire support systems, will be able to not only outrange American and NATO guns, but decimate formations.

In a column for the Association of the U.S. Army, Col. Liam Collins and Capt. Harrison “Brandon” Morgan note that the Russian army is reactivating “its heavy artillery forces, beginning with its 2S7 Pion, mounting an impressive 203 mm round with a maximum range of 37.5 km” (about 23 miles).

In addition, the Russians are currently in the process of reactivating the 2S4 Tyulpan heavy mortar, which fires a massive 240mm round — double the U.S. military’s heaviest 120mm mortar round — at a range of 9,650 meters, or nearly six miles.

The United States’ 155mm artillery pieces have a range of about 22 kilometers (13 miles), meanwhile, and are smaller than the Russian 2S7 Pion’s 203 mm rounds.
