Just finished the first combat platoon plus the attatched panzerschreks. I used Battlefront's urban rubble bases, I think they were ok but left just as much work, if not more, to hide the gaping holes around the figs. The oldest of my FJ figs, old V1 Battlefront guys, had rectangular bases that had to be trimmed before they would fit in the indentations. Ultimately, I could have been happy just using some of the inserts to add some interest, but I'm pretty happy with how they turned out.

The BF urban rubble bases were kind of a pain, but added some nice texture variety.
