That's why every fire mission targeting a single tank gets up to date satellite images, high res thermal drone photos, and dedicated analysts reviewing the intelligence.
At least, that's according to other users in this comment section.
And here I thought it was forward observers and drone pilots using whatever off the shelf drones they have available.
It wouldn't even be true for the US Army, although they would have better unit level technology i.e. military grade recon drones, but yes, also potentially access to ISR.
I was being sarcastic, because the replies I read were so ridiculous e.g. all artillery recon had analysts reviewing thermal, IR, satellites, etc. to determine if a lone tank was real, or a decoy.
