Here are five types of Roman crowns awarded to military personnel:
Corona GramineaGrass Crown
Made from grass of the battlefield for saving an entire legion/army.
Corona CivicaState Crown
Oak leaves for saving lives (ob cives servatos) ["The Imperial Reliefs from the Sebasteion at Aphrodisias," by R. R. R. Smith; The Journal of Roman Studies (1987), pp. 88-138.] and holding ground in battle. A gilded corona civica was given to the triumphator. From the time of Claudius, the corona civica became an imperial attribute. Since the oak was sacred to Jupiter, giving the crown to emperors implied Jupiter's sanction.
