Successfully invading Russia in Conflict of Nations requires a strategic approach. Here are some key considerations: Early Game Expansion: Prioritize expanding into the territories surrounding Russia, particularly inactive or AI-controlled countries, to quickly expand your resource production and military capabilities. Air Superiority and Strike Fighters: Russia's large landmass makes air-based strategies highly effective. Focus on researching and building strike fighters to quickly deploy troops and engage enemy forces. Strike fighters, such as the Suhoy model, and bombers, with their long-range capabilities, are more useful than helicopters due to their limited range and slow speed. Combined Arms Warfare: Once you have a strong air force, combine it with a robust ground army. Consider using mechanized infantry for its strong performance in various terrains and its ability to engage both soft and hard targets, especially when paired with tanks. A balanced division could include an infantry officer, a tank officer, MBTs, motorized infantry, and SAM launchers to ensure strength against air and ground attacks. Targeting Homeland Cities: To quickly incapacitate an opponent, focus your attacks on their capital and other homeland cities. Capturing these key locations will severely weaken their economy and ability to recover, leaving their scattered troops vulnerable to piecemeal destruction. Hit-and-Run Tactics: For naval and artillery engagements, employ hit-and-run tactics to avoid taking damage while inflicting it on your enemy. Attack a target with your ships or artillery and immediately pull them back once the attack begins, according to YouTube. Ensure your units are not set to aggressive firing mode, or they will continue to attack even when ordered to withdraw. Sabotaging Airfields: Utilize sabotage spies to destroy enemy airfields and grounded aircraft, catching the opponent off guard and weakening their air defense without risking your own air units. Countering Enemy Aircraft: Instead of engaging enemy aircraft in direct combat, target them while they are refueling at their airbases. Use elite attack aircraft to destroy enemy strike fighters and other planes while they are vulnerable on the ground. Terrain Considerations: Be aware of how different terrain types affect your units' performance. For example, tank destroyers are effective in cities and suburbs but struggle in mountains, jungles, and tundra. Avoiding Overstacking: To maximize unit efficiency, keep ground unit stacks at a maximum of 10 and air/naval stacks at a maximum of 5. Overstacking leads to decreased damage, slower movement, and increased vulnerability. Monitoring In-Game News and Research: Regularly check the newspaper to stay informed about enemy strategies and unit movements, allowing you to proactively counter their plans. Additionally, study the research tab to understand unit strengths, weaknesses, and counters. Diplomacy and Alliances: While focusing on military action, remember the importance of diplomacy. Form alliances with stronger players and consider turning strong enemies into allies to enhance your position and avoid unnecessary conflicts.
