Ok thanks guys this helps a lot cause I got iron banner rank 5 and need to buy the scout rifle and fusion rifle thanks

If you get some vex glimmer drop consumables and then go to the citadel on Venus (go left from spawn) you can get quite a lot of glimmer from the two axis minotaurs that spawn about every 30 seconds, as well as from the rarely-spawning axis hydra and the occasional axis goblin or hobgoblin. It's a lot of enemies in a relatively small space. I just discovered it for the first time in patrol mode today (other than the times I went there in story mode, and I didn't have a lot of time to look around then) it's a good place to farm, and a fun place to play around and do anything from meeleing through goblin hordes to having sniper battles with hobgoblins who are at the edge of your range.

Personally what I do is do "The Dark Below" mission on the moon on Level 9, get to the gate where lots of enemies run out and just kill all the enemies but leave 1 yellow bar enemy alive to kill you. Make sure to use the item which lets you get more Glimmer from Hive enemies, the Black Wax Idol.
