PIP offers Arma III the opportunity to modernized combined arms in a way that no other game allows (Save for dedicated sims). As it stands PIP makes a nice impact in gameplay but it is but the first stages to make this feature truly stand out. It offers more imerssive effects than going into optics mode, however due to the lack of zoom and camera mode functions, it seems more like a gimmick by comparison.
The first thing is thermal tweaking which I cover here http://feedback.arma3.com/view.php?id=2899 the second major step is having the ability to zoom. As it stands, PIP is only useful for close range warfare, which harms the possibilities it could have both in gameplay and modding.
Recon, long range assault and navigation would be the most prevelant for vehicular use. The ability for say the Ifrit & Hunter to double not only as combat but also recon unit, to scan the horizon from afar, or to be at a UAV station without having to actually go into optics mode unless desired.
Likewise it would give aircraft a new method of attack, give pilots the opportunity to see what their CPG is looking at to better coordinate and more.
Finally, on its own PIP should have the option to change camera modes, from DTV, NV and FLIR just as optics can, however if that is not possible then above would be fine enough. {F17524}
