Now I was looking at video from the fighting in Syria, and saw people complain that the other side was shooting with anti-tank weapons that outrange them…

…some ‘people’ are never happy! :rolleyes:

But I’m sure Google will be thrilled you’ve thought of using their phone to solve this ‘problem’!

Mortar rounds are inherently inaccurate: the rounds are slow, so have a long flight-time, they have a high trajectory so pass through different layers of differing wind-speeds and the rounds are not spin-stabilised…

…they are pretty unsuitable for targeting moving-targets, even if you do have an exact range and GPS position.
