How to merge regiments into an army?

It is really frustrating not knowing how to, 'cause I end up losing battles because I only have 1000 soldiers to use for the fighting.

Have the regiments in the same province, click and drag. A list of the regiments will pop up and there will be a small button above this with a symbol - two arrows pointing towards one another. That is your merge button.
