A senior military officer has now told the BBC that Ukraine's armed forces hope to recover the city of Kherson within weeks after discussing the beginning of a counteroffensive in the south for weeks.

They are anticipated to employ a different strategy with a role for tiny drone units rather than a significant full-scale assault.

When a member of Ukraine's special operations forces discovers an armored vehicle buried in trenches, he controls a drone hovering over Russian positions while keeping his eyes riveted to a monitor and issues the order to an artillery unit to "fire when you're ready."

This soldier, whose call sign is Maverick from the film Top Gun, must conceal his identity because Russian lines are only 3 kilometers (1.9 miles) away.Maverick and his squad are tasked with locating possible targets and relaying their coordinates. They then observe and fire.Large-caliber weapons are crucial in this fight.

"This is a battle of artillery, cutting-edge weapons, and brainpower. Although the soldier still has a crucial role, airstrikes, artillery, and rockets are largely responsible for success "Maj. Gen. Dmytro Marchenko, who organized the defense of Mykolaiv, a city in southern Ukraine, against a Russian onslaught last spring, says.

He claims that it is not like World War Two, when one large army assaulted another.

And that's what the Russian offensive in Ukraine's eastern and southern regions has been based on. Russian artillery fires unrelenting barrages that flatten everything in their path, including military installations and residential areas.

In response to Kyiv's lauded counteroffensive, the Russians, according to Ukrainian authorities, are deploying an additional 30 battalion tactical groups, or about 22,000 soldiers, to the south.

The use of American Himars and M270 multiple rocket launchers has enabled the Ukrainians to destroy previously inaccessible sites.

However, they claim that more are required to repel Russian fire and strike important targets such air defense, ammo stores, and supply routes.

Maj Gen Marchenko predicts that they will retake Kherson "shortly"—within a few weeks.

But for them to work, they must undermine what he terms Russia's static defense approach: "We need three times as much power, ammunition, and artillery.

Unfortunately, we lack such a benefit. Because of this, we must take unconventional action to dislodge them from their positions and balance our power and resources."

Undoubtedly, one of their unconventional strategies entails the coordination of aircraft surveillance groups and artillery. That might make it easier to encircle Russian forces without suffering the kind of devastating losses that would be inevitable in an open conflict.

Maverick adds, "We have crossed the River Inhulets, and now we're aiming to expand that area, introduce more equipment, and divide the Russian forces here into two groups—Kakhovka and Kherson."

Severing Russian supply channels in the south is a crucial component of their strategy.

According to Maj Gen Marchenko, the Ukrainian military has destroyed "more than 20 ammo depots [in the Kherson region], many command and control centers, and other targets, including strategically significant bridges" in just two weeks.

Even though Ukraine hasn't formally admitted responsibility for those attacks, Kherson and Nova Kakhovka's bridges across the River Dnieper have been frequently attacked, as have recent explosions at an airbase and an ammo depot in Crimea.
