She should be in little danger as long as she steers clear of the Mecha Tengu escorting each Battleship pair.
When the 8 Shogun Battleships appear, use Natasha to destroy them while the rest of your army defends the fortress. Have her wipe out the infantry and use the Bullfrog on that side of the river to send her back to the fortress. When the secondary objective appears, use the Bullfrog to transport Natasha across to the Hermitage. When Conscripts become available for production, build 4-5 of those to kill the Tankbusters the enemy Sudden Transports will soon be dropping at the gates. Flak Troopers should prioritize Chopper-VXs since Natasha cannot call air strikes on those. After Kenji arrives, Tsunami Tanks and Striker-VXs start attacking from the southeast and southwest. After the cutscene, train 5 Flak Troopers while Natasha destroys the north gate and takes out the Tankbusters outside it. Do not waste time attacking Tankbusters until they surface. Kill the infantry outside, call an air strike on the gate, and kill the infantry inside. = Soviets 1: Leningrad The Shrike and the Thorn = Starting Resources: 0 Starting Buildings: None Starting Units: Natasha Produceable Buildings: None Produceable Units: Conscript Flak Trooper Top-Secret Protocols: Magnetic Satellite Objective 1: Secure the Fortress Objective 2: Train 5 Flak Troopers Objective 3: Protect the Fortress Objective 4: Destroy the Battleships Secondary Objective 1: Save the Hermitage Walkthrough: This mission is essentially a tutorial, so follow the prompts. It may not have a complete list since some need to be triggered, and it does not give advice on clearing them unless they make the mission easier or are trivial to complete. This guide does not stress secondary objectives. This walkthrough is based on playing Solo on Hard difficulty by a player of no great skill. The methods detailed here definitely do work, but there is no reason to follow them slavishly.
