One weapon being utilised by the Ukrainian military is the German PzH 2000. Germany and the Netherlands donated 12 such self-propelled howitzers to Ukraine.

PzH 2000 or Panzerhaubitze 2000 is a German 155 mm self-propelled howitzer developed by German companies Krauss-Maffei Wegmann (KMW). The howitzer is based on a tracked armored chassis to offer high mobility in all-terrain conditions and protection for the crew against the firing of small arms and artillery shell splinters.
Another weapon being used by the Ukrainian military is French Caesar self-propelled howitzer. The CAESAR is a wheeled, 155mm 52-caliber self-propelled howitzer. It holds 18 rounds and is typically operated by a crew of five, though if necessary, the CAESAR can be operated by as few as three persons. It has a firing range of approximately 42 km using an Extended Range, Full Bore (ERFB) shell, and more than 50 km using rocket assisted shells. The system is integrated with a fully computerized system, providing automatic control.

The PzH 2000 has a maximum off-road speed of 45 km/h and fires accurate rapid shots. At the same time CAESAR’s off-road speed is up to 50 km/h, but it has maximum on-road speed of 100 km/h. Caesar self-propelled howitzer can launch 155 mm shells at a distance of 40 kilometers at a speed of six to eight shots per minute.
This allows personnel to fire and leave the area before the enemy has time to fix its target and return fire.
