In this coloring page, four tan-colored tanks are lined up in a row. Each one appears to be constructed of metal, with wide guns mounted to the front side of each tank and a few people stationed on top. The first tank is adorned with a waving flag, while the ensuing tanks feature mounted machine guns. You could bring this scene to life by differentiating each tank's body with colored shades and patterns, while giving the guns a gunmetal grey coloration. Outline each of the figures atop the tanks in black, then give them skin tone to create a realistic feel. Add blue and yellow to the flags, and accentuate the details of the machine guns with silver and black. Lastly, use a terracotta hue to bring the landscape to life.
