Continue your push to the east and gain control of the area where the three Oil Rigs are located. You don’t need to hold this ground permanently at this point; simply provide a breathing space where your MG Infantry can capture the Oil Rigs (Paratroopers work nicely, but you can send them on foot or in a Halftrack APC if necessary). You might not get them all at this time, but try to get at least two of them — you desperately need the Resources. Continue your advance a bit more and take out a few Soviet Bunkers; if you had the Force Shield Generators, Bofors, and Zsu 37s protecting you chances are you can push ahead and destroy the base. This will drastically reduce the number of Soviet aircraft overhead, and eliminate some of the Ice-Bomber attacks. If it looks like you’re too weak to take the base, curl back and retreat to a point close to the captured Moving Giant Turret Factory to lick your wounds and await reinforcements from your base.
Speaking of the base, things will be getting awfully hairy there by now. APC Mole and Partisan attacks will have you frantically erecting Pillboxes and sending out cheap armored units like Matildas and Halftracks to fight them off. Just keep your cool, use the “Repair All” button as necessary, and remember to build an Aero Research Facility as soon as you can: it’ll provide you with better planes and a steady source of income if you upgrade it with Homeland Shipments. As soon as you have a few extra resources, upgrade to Tech Level 3 to access the more powerful weapons you need to wage this battle. Also build at least two (preferably three) Airports. You’ll need them when the call comes from Hellmann that he needs help defending the Radio Station they’ve captured but which lacks power.
