i was recently able to take a brief look at Chris Kemp’s model collection and how he organises it . See http://www.notquitemechanised.com
Chris has set his battle scale at (I believe) 1 unit/base =1 battalion. My basic scale is 1 strategic unit = 1 battalion, and 1 tactical gaming unit is the company of 2-4 platoon bases.
But there is still so much that all wargamers can learn from each other’s gaming methods. If I have taken nothing else from Chris’s collection, I have learned about how to box and categorise units. With my gaming method I do not have the luxury of identifying each individual unit, but I can at least store and label units as “Rifles, MG, Mortars, HQ, AT”, etc., with their nationality and type (Para, Regular, SS, Mountain, Commando) and so on included. In one box I can store 12 platoons or 16 vehicles. I am finding this is a great way to proceed.
in the same way, small terrain may be stored.
