I was highly thinking of garrisons markkur, but I did want this to be militia only

They would definitely work well in defensive roles allowing militia infantry to attack, but I eventually decided to stick with only militia, and to make specialised defence corps to fill the role of garrisons.
To be fair yearzero, this is double the numbers that I usually get when declaring war on the SU, so I was quite happy to see it so high

My manpower is sitting at a little over 1000.
I've been very busy and slightly forgetful recently, having had a short river holiday, new years and Christmas, and several birthdays. Maybe update tomorrow, maybe not.
