Ranking up is fast at first. As you progress to the upper ranks it gets harder as it requires more and more points with each next rank. It also depends on the game mode that you play. If you play Conquest you can expect to get less points. In Rush mode you can really pile up points. Also, the more you kill people with weapons the more you get bonus points. You can get a Bronze, Silver, Gold and even Platinum star for each weapon. The Gold stars reward 5,000 points each and the Platinum star is 10,000 points. If you look at my stats under Insignias you will see more ways to earn bonus points (500 head shots for example is a 10K bonus).
Using the Medic class is also a great way to get a lot of points. You get points for healing people and major points for reviving people. Stick near your squad members and you get double points for healing or reviving them.
You will have the benefit of improved accuracy in guns as well. When the game first came out the guns were not as accurate. Through patches EA has improved the game and all weapons are more accurate. So be careful and don't run out in the open all the time.
Grenades can be lethal. You can cook them too. I generally toss them where I see people around a flag or inside buildings. There are specializations (perks) that can add to the explosive power of grenades. You are limited to one grenade unless you use the Grenade Vest specialization. Which is good because then you don't have a typical nade spam all over the place like in Modern Warfare. Expect a lot of tubers and people firing rocket launchers at close range.
Tanks are pretty powerful. There's a ranged hit on them so you can fire at the ground if you see an enemy and they will go flying through the air as they are killed. APCs are decent. They fire in 5-6 round bursts. There are vehicle specializations to add range, armor or secondary weapons such as a machine gun on the tank turret or missile launcher on the APC. The UAV is quite lethal too. You can spot people with it and fire devastating laser guided missiles. You can even equip it with a pair of guns so you can mow people down from above.
