Now that I am getting back into some miniature wargaming, I think I'll discuss a few things I typically use.
My figures are mounted on single metal bases I cut from scrap from a local metal shop. For aesthetic purposes, I flock these (usually green grass, but sometimes a sandy tan).
My movement trays are actually good strength strip magnets, stuck down to heavy cardboard stock and flocked a color depending on which side they are (black and tan). There are 3 sizes. I can then put as many figures as needed to create a unit on a base, and allow removal of figures when they are casualties. The good magnets allow the trays to be moved without knocking over individual figures.
Another good feature is that it allows me to mix and match forces as needed (e.g. allies) from the different nationalities I have, with minimal confusion as to which side those forces are on. I can even have deserters from one side set up on opposite sides. For an some pictures of the bases in action, look at the archive from back in January last year.
This flexibility allows me to mix and match bases as needed. For example my DSR Mass Battle ruleset (DSRMB), each unit actually takes up 2 hexes, so there are 2 bases placed side-by side per unit (although skirmishers can move seperately). I get the bases out, set the figures on the bases, and off the battle goes.
Most of my rules use hexes of various sizes, although the most common is a 3" grid. The grid makes the game go by fast (something I strive for in my rules), with no measuring needed.
I handle terrain in 2 levels- I have color acetate sheets with various hills, woods, and streams that I lay down. I can play the game that way or if I want a more 3D effect, take the time and lay out various tree clumps which are removeable if a unit wishes to move into that hex. For a good example, look back in the archive to June of last year for my terrain templates and my tree clusters.
Its a simple system that is very flexible. If you have any comments or suggestions, please let me know- I'm always open to new ideas.
