Ukraine has, in the last few days seized control of at least
1,250 sq KMs of Russian territory and 92 settlements.
Ukraine used manoeuvre (Mechanised Brigades and
Drones) to strike fast and deep into the Russian territory:

• Six brigades, mostly equipped with western tanks
  and armoured fighting vehicles.
• Light reconnaissance groups moved as vanguard
  to confuse the enemy about the intentions and
  target of the main force.
• Ukraine managed to establish an Air Defence and
  Electronic Warfare bubble over their advancing
  forces.
• It was indeed a successful ‘Manoeuvre Battle’, in a
  war which had slipped into a slugfest of attrition
  and destruction.
  Their Op Security was airtight, even the Americans were not possibly aware of the operation. The Russians certainly were surprised. In this era of ground, air and space surveillance, the force that achieves surprise deserves victory.
  Ukraine army picked a weakly defended stretch near the Russian town of Sudzha, 10 KMs from the border. The nearest active frontline is at Kharkiv about 200 Kms Southeast. Russian surveillance elements were low in the Kursk sector which was perhaps never appreciated to be threatened.
  Ukraine army continues to surprise, they have successfully used First Person View (FPV) drones against Russian Attack Helicopters. It requires excellent skills to crash the drones into an airborne Attack Helicopter; after considerable recent successes, Russian Attack Helicopters are in for some scare.
• Morale plays an important role in any war:
• The morale of the Ukrainian Army and the Nation has got a huge boost, a reason to smile.
• While the Ukrainian push is mainly into the Kursk region, Russian citizens are now also being evacuated
  from the neighbouring region of Belgorod. People are scared and upset. While morale is visibly low,
  there is no clamour for a regime change ……. yet.
• What needs to be watched keenly by Ukraine is whether the Kursk operations will bring relief for the
  beleaguered defenders in Donetsk.
  According to RBC Ukraine News Agency, Putin has ordered his forces to push back Ukrainian troops from
  Kursk by 1 Oct. Russian forces are reportedly already operating in the salient disrupting Ukrainian supply lines.
  Also, Ukraine may not have enough boots on ground to exert control over the entire area they claim under
  occupation; the Russian counteroffensive may come sooner than later.
  As of today, Russian forces have managed to recapture the settlements of Olgovka and Kremyanoye.
  Conclusively, Ukraine’s Kursk offensive is a high risk and high stakes operation. If they manage to hold onto the
  vast captured real estate, they have a good hand at any future negotiation table.
  On a lighter note, the war has many …. Lets just say humorous geopolitical angles to it ……. Natural gas flowing from West Siberian gas fields to Europe via Ukraine passes through a metering station near the border in the Sudzha district.
  And,
  Gas has continued flowing on to Europe despite the war, allowing Russia’s Gazprom natural gas giant to earn money from the gas and letting Ukraine collect transit fees!!!!!
