Wow, it's kinda funny how you keep running into your online buddies in the same posts, talking about the same things!! As a lifelong armor builder and Soldier, I never thought that my model skills would be of any use to anyone other than me.
As an anti-tank platoon leader, I saw that our ability to ID tanks was pretty bad. Every Soldier was pretty proficient at IDing tanks with the GTA card deck; three views, all line drawings. After a few sessions, you could memorize the deck and move onto the next gunnery skills test.
I went to the local TASC and pulled out a box of the 1/35th scale of ID models and found that they were useful, but only up to a certain point. Like some of you guys, we set up a scaled distance range and used these TASC kits augmented with my armor kits to make tank ID more of a challenge. Our Dragon and TOW gunners ate the training up and improved their skills. After the ID became more proficient, we'd set up 'shoot/don't shoot' scenarios, placing the models in hull down positions, moving to cover at X speed, etc. Like you guys, it was a proud moment when my model building combined with my real world job to improve training.
Thanks for sharing your stories, guys!
