There is a technology called CRISPR, which is a real thing and that could be also used in a World War 3. It changes genes into a wanted form, which can have many benefits. There can be soldiers with improved good muscles with like 20% damage bonus, or enhanced intelligence... this could be an option in research where you can also upgrade the technology and when upgraded give serious power bonus to the infantry and it can also visually improve the troops and it will be a great thing to make troops stronger except upgrading their equipment. It can also make a morale bonus to the whole country. This would make genetically-enhanced supersoldiers and also make the game more colorful and interesting. This is just a simple idea, the developers can make it more complex and more interesting.
