Futuristic soldier with backpack

This is a clean, flat-style digital illustration showcasing four distinct character classes arranged in a row against a solid cyan background. From left to right, we see, a sci-fi soldier equipped with a full helmet and field backpack, rendered with bright blue and white accents. Next is, a classic medieval knight clad in silver steel plate armor featuring prominent horns on the helmet and a blue cape. Beside him is, a rogue archetype wearing a green hooded cloak and leather gear, brandishing a dagger. On the far right stands, a modern-day combat soldier in camouflage gear, holding an assault rifle. The art style is minimalist and stylized, likely for a mobile strategy game or icon set, using bold outlines, vibrant colors, and simplified shapes to convey character traits at a glance. The lighting is uniform and soft, lacking heavy shadows, emphasizing the iconography over realistic depth.
