Also, if the game is really close near the end, be careful not to die.
For example, your team is either winning, on points and you just have to hold on. Or it is looking like your are going to overtake the enemy right at the end, because you have 2 caps, and the enemy has one, and they have less than double your points left. i.e. you have 200 points & 2 caps and they have 300 points and one cap.
At this point, if you are in a squishy vehicle, be VERY careful not to get killed: deny the red team those extra 25 points. Up to the point of just hiding. A few matches have gone either way, depending on a few kills in the very last seconds.
