A realistic modern military-style window, designed with a rectangular frame made of sturdy metal or reinforced plastic, featuring a clear glass pane that may have minor scratches or smudges for added realism. The window frame includes subtle weathering effects like chipped paint or rust, depending on the environment it's placed in, and may have a simple latch or lock mechanism for functionality. The glass could optionally have a slight tint or reflection to mimic real-world windows in military installations.
