Nice batrep, sounds like a very fun game was had by all participants, as it was a very close game. My kind of battle!
If you are interested, it is very easy to make smoke markers to scale. Get some pillow stuffing from your local fabric store (white). Get a can of black spray paint (or whatever colors you want/need), and spray it directly onto the filler material: it won't cover it very well, creating a varying color of tint, throughout it. you can glue 3mm thick chipboard into an upside-down T-shape, gluing the painted smoke to the upright chipboard, covering (hiding) it.
You could also use PVA Glue to attach unpainted cotton balls, stacking them as needed. I did this early on in my Army Men games, to make circles to mark off Smoke Grenade circles on the tabletop.
I used this technique to make billowing smoke tufts to place on top of my Army Men Tanks and vehicles when they get destroyed. These were sprayed with black paint, then pulled and manipulated to make clouds, as needed. If you want darker, apply more paint -- it creates its own shading effects, with little effort. It can also be used to form smoke rings/squares/etc., as needed. Cheers!
