Ukrainian military officials released video they say shows what a day in the life of a commander of a self-propelled howitzer looks like.
The video is shot from the point of view of the vehicle's commander, who spends a considerable amount of time with his head out of the hatch, directing his men, and shows the machine in action.
The soldiers inside the vehicle can be seen repeatedly firing shells before reloading.

Self-propelled howitzers, while similar to tanks, are usually much more fragile and are fundamentally different in that they cannot usually withstand direct missile from heavy weaponry.
On the other hand, their long guns can fire much further than a tank's gun. They also do not require direct line of sight to hit their targets, unlike most tanks.
The images were obtained from the National Guard of Ukraine on Friday.
They were also relayed by the Western Territorial Administration of the National Guard of Ukraine, who said that the vehicle was a 2S1 "Gvozdika," which means "Carnation" in English. The 2S1 Gvozdika was originally built by the Soviet Union and entered service in the late 1970s.
The National Guard said in a short statement that the footage shows "what the departure of artillerymen of the National Guard of Ukraine on a combat mission looks like through the eyes of the crew commander."
They added: "The Guardsmen are attacking the enemy in the Luhansk Region."
Russia invaded Ukraine on February 24 in what the Kremlin is calling a "special military operation." Friday marks the 128th day of the invasion.
The General Staff of the Armed Forces of Ukraine reported that between February 24 and July 1, Russia had lost about 35,750 personnel, 1,577 tanks, 3,736 armored combat vehicles, 796 artillery units, 246 multiple launch rocket systems, 105 air defense systems, 217 warplanes, 186 helicopters, 645 drones, 143 cruise missiles, 15 warships, 2,610 motor vehicles and fuel tankers, and 61 units of special equipment.
A missile strike on Odesa killed 19 people, including two children, according to regional governor Maksym Marchenko, with more than 30 people hospitalized. Ukrainian Brigadier General Oleksii Hromov said that Russia is using inaccurate missiles from old Soviet stockpiles in over half of its strikes on the country.
Ukraine's top brass has said that they have forced the Russians to abandon Snake Island and have derided Kremlin officials for claiming that they left as a "gesture of goodwill." Ukraine's military added that the Russians had fled the island in speedboats after being hit by a barrage of missile strikes and artillery.
The situation in the eastern Ukrainian city of Lysychansk has been described as "extremely difficult," with Russian shelling making it impossible for civilians to evacuate.
U.K. Foreign Secretary Liz Truss said that pushing Russian forces out of Ukraine completely was a "realistic" ambition and justification for providing additional weapons.
Russian Foreign Minister Sergei Lavrov said that a new "iron curtain" is appearing between Russia and the West.
Russia accused Norway of disrupting critical supplies from being delivered to Svalbard on Wednesday, threatening to retaliate. But Norway said that it was not blocking access to the archipelago in the Arctic, stating that it was only applying international sanctions and that the Russians had other ways of getting there.
