How did I get kills without gunship or missile as a commander?

I was getting kills without the gunship or missile deployed. All I remember I had deployed was the EMP UAV, and every few seconds, I was hitting a tank and was gaining points right up until I got 100 points, then I got the kill.

How on earth did I kill that poor guy?

Edit
It seems that the EMP UAV damages tanks too - but not all the time! Hence why I was so confused yet happy when I killed that guy.

Update
I had this happen again over the weekend, but I was on my iPad when it happened - and I can confirm that I had:

• No gunships deployed
• no EMP or UAV deployed
• On Rogue Transmission
• Just captured point C (Gunship point)
• on my iPad

I then lost connection, after the second time it happened, to the server.

Solution 1:

If your team captures the control point where an enemy gunship is deployed, the gunship will take damage until it gets destroyed.

Are you aboslutely sure you killed a tank with it? I didn't think EMP UAVs damaged tanks...that would be wayyyyyy too easy. I've dropped it over an enemy gunship and that damaged (and killed) the gunship, but I am convinced that EMP UAV does not hurt armor.

Solution 2:

Since it isn't clear if you mean that you didn't deploy a gunship or if there wasn't any at all, I suggest that you destroyed an enemy gunship with an EMP UAV.

Or you dropped a supply crate on the head of a poor bastard unlucky enough to stand there:

The supply drop can also be used to crush inattentive enemies, especially snipers. For this feat, the commander is credited with a generic kill against the victim.

Edit: I now had the same thing the OP described and it was no gunship and no supply drop. It really seems like the EMP is also damaging other vehicles. This needs testing and more evidence.

Solution 3:

If an enemy commander deploys a gunship and your team takes back the flag that grants the gunship, the current enemy gunship will take damage out of nowhere until it explodes. If there are still enemies in the gunship when it explodes, the kills are granted to you as commander, even though you did nothing at all.
