well you have to kill off the towns defences wich every town has posted ai so you cant just run in and take it. you have to set a mission wich can be called a quest in order to get rank. rank can be considered lvl couse the higher rank you have the more command you have and other vehicles. rank is a grind in the end but thats last ranks. yea. so ai can be considered monster,missions looked at like quests, and grind can be considered geting your rank up. yea all while holding gun or what ever you are at the time.
