I did bunch of coppers last year (?). I spent some birthday cash this fall to buy some reinforcements. The only pack I didn't have was the heavy weapons group. Not sure Commissioner Gordon really needed these fellows (and the worry is always that he's use them to suppress the poor, rather than against super villains), but I had the cash, so... .
The machine gunner was a surprise. I see (suddenly, in this very picture) that he has a shoulder patch that none of the others have. So I will go back and paint that (argh). The crate is from a "clues" pack that I have underway.
I can't tell what this guy is supposed to be holding? Just a large calibre rifle? Doesn't look like a shotty.
Perhaps Chief O'Hara from the original Batman TV series?
I was trying to match these to the colours I used last year. I think I was close on the blue (chose one paint pot to the right, I think). The basing is different but I have since gone back and matched the darker grey.
