Am I able to use up to my army cap now? The army creation system is a bit unclear to me.

Extract from your nation card:

Military

Army Cap: 105,000
Army Replenishment Rate ( Per season): 2,000
Army Cap Increase Per Territory: 10,000

Militia Cap: 155,000
Militia Replenishment Rate (Per season): 2,500
Army Cap Increase Per Territory: 15,0000

============================================

So in conclusion, you can replenish your army at a rate of 2,500 militia and 2000 professionals per season. 

Before you bring the "but look at the areas I own, surely I can make more than that in a season?" out of the bag, I will put it to rest right now.

The reason replenishment is set quite low, and you cannot change it, is to create a strategic aspect of the RP that requires CAREFUL planning, and prevents kids from blitzkrieging across the world like they do on every other NRP. 

Attack, claim land, but do not over extend yourself and sometimes you will need to go on the defensive.
