Some things about the Russian war in Ukraine are clear - Russia has failed to take over the key cities it had hoped to smother, and in many places its invasion has largely stalled.
Other aspects are far harder to get a clear grip on - Is Russia changing tactics, being beaten back or both?
These questions are made harder by the relentless information war being waged on both sides - conflicting narratives designed to aid their own causes.
While the Russian advance has no doubt slowed, what this means for the huge military's next steps and the innocent people it is invading remain largely unclear.
Is Russia regrouping?
UK Foreign Secretary Liz Truss has warned that Vladimir Putin may be intending to use peace talks pushed for by Ukrainian president Volodymyr Zelensky as an opportunity to regroup his forces.
She said she was "very sceptical" about the Kremlin's position, telling the Times: “If a country is serious about negotiations, it doesn’t indiscriminately bomb civilians that day.”
She said the talks could be a "smokescreen" warning that “what we’ve seen is an attempt to create space for the Russians to regroup”.
Are Russian forces pulling back?
Reports claim the Russian military’s strategy has changed, no longer focused on taking certain cities with troops on the ground but instead dropping back and raining artillery shells down on the civilians.
Heavy bombardments of densely populated areas is now a primary tactic, similar to those used in Russia’s wars in Chechnya and Syria.
In a tweet, the UK Ministry of Defence said that Russia has "been forced to change its operational approach and is now pursuing a strategy of attrition", and turning to "indiscriminate firepower" as a tactic.
Statements about any kind of Russian pullback being intentional has been heavily disputed by Ukraine, however.
Ukraine insists Moscow has lost its ‘offensive potential’ after its own armed forces pushed Russia out of Makariv, a tactically significant suburb of Kyiv 37 miles to the west of the capital, “thanks to the heroic actions of our defenders”.
UK intelligence appears to corroborate this, with the latest report saying Russian forces remain “largely stalled in place”.
Meanwhile, in the south of the country, Russian forces are still unable to take the port city of Mariupol despite Ukrainian fighters and citizens being under heavy siege and surrounded on all sides.
On Tuesday March 22, the Ministry of Defence tweeted: “Despite heavy fighting, Ukrainian forces continue to repulse Russian attempts to occupy the southern city of Mariupol.
“Russian forces elsewhere in Ukraine have endured yet another day of limited progress with most forces largely stalled in place.
“Several Ukrainian cities continue to suffer heavy Russian air and artillery bombardment with the UN reporting that more than 10 million Ukrainians are now internally displaced as a result of Russia’s invasion.”
Are Russia and Ukraine running out of weapons?
On March 22, Ukraine claimed Russian forces had just three days of supplies left after supply chain breakdowns - a claim hard to verify given that Ukraine too is thought to be running low military equipment, with its own supply line reliant on allies.
Western sources have said that the supply chain claims are ‘plausible’, but hard to nail down as fact.
Nick Reynolds, a land warfare specialist with the Rusi thinktank, told the Guardian : “Resupply issues are hard to gauge, as both sides are keeping that information close to their chest due to operational security concerns.”
