Sometime last century I started buying Ground Zero Games 25mm figures.
They were great, but as time went on, other things distracted me and they are sitting in the loft awaiting rediscovery.
A few years ago, I decided to buy some of the 15mm figures, but they sat in their bags for a while.
While looking for something else, I found them and decided to put them together.
The NSL Power Armour is equipped with an "Anti-Personnel" weapon and optional twin missile pods.
Somewhere I have the Stargrunt rules which might remind me of the details of the weapon mix.
