Military vehicle, fighter jet, dog tags and naval ship icons

A simple black line illustration presents four military-themed icons arranged in a clean 2x2 grid on a white background. The top left shows a tank in profile, while the top right depicts a fighter jet viewed from above. Below, a pair of dog tags hangs at the left, and a naval ship sits at the lower right above a stylized wave line. The minimal vector style uses bold outlines, generous negative space, and no color beyond black and white. The layout feels orderly and graphic, making it suitable for defense, transport, or military concept design. Each symbol is isolated and easy to read, which also supports editorial layouts, presentations, and web use.
