Thanks Baz. I've just gone for the free lite version for now, but it looks like it has possibilities. One problem I foresee straight away though is the accuracy of the GPS plot. Even with a dedicated handheld GPS receiver 25m isn't a bad margin of error and the default setting for notification on Battle Tac is 100m...
A 200m circle from where you actually are: that's from behind enemy lines to too far away to make much difference! I could see it being handy for finding your squad after regen on a very big site and, on an urban site, maybe with its own and/or surrounded by WiFi connections, the accuracy could be good enough to use tactically. I have a 'GPS bells-and-whistles-iser' app on my phone which helps GoogleMaps sort its sh!t out faster and, I think, better, so maybe that will help. So far Battle Tac thinks I'm reclining in the road outside my house, rather than on my bed, and we have 3 WiFi connections currently active in this building and over 20 detectable in the surrounding area... (it's a high student to luddite ratio demographic)
There is the cool factor which shouldn't be overlooked, I think. The whole mil-tech & being in a vid game vibe - the template communications, NATO symbols, security, etc. Much cooler than just texting each other.
