It is. The game is still under-developed and rather than shove combat out, with little other features available, the admins are gradually adding in features (such as creatures and R&D) as a build up towards combat. There is a feature called Arrest and Execute, which is pretty much a form of combat that is available to those in a faction (best to ready the rules about it for a good idea).
There are plenty of other features to do in the combine, so don't worry about not having anything to do til combat is released.

There are also NPC brawlers with which you can fight. Fighting a brawler gives you XP, regardless of if you win or not, and neither one of you can die, but merely be subdued to 1 HP.
