Dies ist eine Karte, die ich erworben habe und die von den Streitkräften der Republika Srpska während der Belagerung von Sarajevo verwendet wurde. Weiß jemand, was diese Symbole bedeuten?

What specifically you want to know?

Bullet / grave looking things are APCs, diamonds are tanks, brackets are defensive lines, the cross looking things are units (battalion, company, platoon, etc,) the arrows are lines of march (for example 2 notches means company, 1 is platoon) triangle / flag is command post… and so on. Red/black would be serbs and blue would be ARBiH

That map is top secret btw.
