The rewards from this quest are small but significant. The player may decide whether they are worth the trouble. It does not take much time to collect the dog tag bags, though. In fact, collecting all three empty bags can be done on a single trip, if you finesse the dialogue options. What takes the time is killing 50 uncommon mobs ranging from level one to 200. Commander Brock will give you a spiffy ring just like his, but you must fill a Dog-tag Bag with the proof of 10 kills of Omni Grunts. Helpfully enough, he gives you a Dog-Tag Bag.
