PS EFFECTS!
Hi there,
I am looking for clarification / explanation on the below effects. Desperately trying to improve my profiecincy and am struggling to find advanced / detailed tutorials. Any insight is very much appreciated, and extremely helpful. Thanks so much!
1. I beleive this is the result of the Bitmap effect, however, I have attempted this to no avail. I cannot seem to achieve the dotted background pattern / overall level of distortion.

2. The central image I believe is layered gradient maps / images — however, how is the background texture achieved? Additionally — how can I achieve the distortion / grain that appears on the central image?
3. How to replicate 'line' texture on letters?

4. Threshold? How can I apply colour to a threshold filter? 
5. Soldier image — is this achieved via Gradient map?
