Eh, getting honor is not about getting kills. Kills only add like +10 to your total experience.
You get experience by completing the objectives, or annihilating the opposite team.
The ammount of experience you get when completing the objective or destroying the other team depends on which mission you are playing.
Keep in mind that completing the mission results in more experience then when you just kill the whole opposite team.
And that just takes some nice teamwork. Not to mention some skills of your own
