Technomancer firing other people's weapons., Erm yeah Options

[Mooseh]

Ok this came up in our session last night. Whilst trekking through a forest we were set upon by a group of lionesses. Needless to say people began shooting instead of running and at this point our technomancer came up with the brilliant idea of shooting someone else's weapon via the wireless smartlink.

So he was trying to shoot someone's gun who had fired on his last round so we figured the weapon was pointing in roughly the right direction but..... what dice to roll. In the end I suggested using Reaction so he basically tell's the gun to fire when he think's its roughly over the target. The reason I'm posting this on here is to find out how other people would have handled this situation.

I'm guessing the majority of people are going to say "Nope wouldn't have let him do it at all its just silly" but whats done is done. ;)
