Hi, I use the Tankers from the Action Fleet range, IIRC. There are Micro Machine figs who are too small except for the Brain bug. Action Fleet has two sizes for tankers. The middle size ones are a great fit for those Gzg bugs. I'm doing Starship Troopers in 6mm. Trying to figure out what to use for Hoppers. I'm producing stuff for the animated series too. I have light mobile infantry ready. Walkers selected. I have 7 or 9 tankers. Over a 100 warrior bugs. Just gotta decide on rules.
Thanks.
John
