When I was in the army (Armored Cav), we would conduct sandbox operations to train on communication, movement to contact and actions on contact with vehicles. The "game" consisted of this huge plastic terrain and small models of our vehicles (M113, M-3 Bradley, M-1 tank etc) we had little periscopes that we used to view the terrain as if we were in the vehicles. The whole thing came in a giant box that looked like a game box. Did anyone else in the service ever train with these? If so, does anyone else remember what it was called? Was it an actual game?
There were "miniatures gamers" of whom 'moi' seen/read about using their own 'fashioned viewers' in a similar demeanor. In fact, some 'photographers' even employed them as such and provided the "playing level views" with these. You should have several assortment of them, so that you have Man-level, Horsed-level, etc.-level means of seeing anything from those differing 'perspectives' in such a demeanor.
Boy, that escalated quickly. I mean that really got out of hand fast.
I was in the Army from 96-99, I was a Bradley Mechanic and saw a lot of the training and stuff the grunts did. Never saw what you are talking about, did see them play with silhouette flash cards to recognize armor both NATO and Russian.
