Abductor has a issue with ranges, it's weapon range is higher than its sight range and it makes the abductor shoot the radar blip and completely miss most of the time (this can also happen with manual targeting, abductor can lose sight before shooting and completely miss) , or shoot a completely different target
some fixes could be :
Improve LoS so the abductor can actually see what it tries to hit
Hold or Return fire by default
(i think these 2 would be the best)
Custom behaviour to emp unit that has been ordered to abduct (could be problematic and confusing)
