Maybe his goal isn't to take over the police world. Maybe he's instead steering the company to win this contract instead. Assuming IVAS works well with the Army, there's no reason something similar wouldn't be adapted for other branches. US Army is like 1M soldiers alone. Who cares about police market if you can do this.
Additionally, 300 degree simulators aren't going to be around in 10 years. AR/VR will. Doesn't mean he can't still sell them while the market is hot, but police budgets aren't known to have hundreds of thousands sitting around and there's nothing he can do about that. If government makes training mandatory or gives stipends/tax credits or whatever and VirTra then doesn't add staff? Then i'll be disappointed.
