# Someone graffiti'd my task list!

I need to perform some maintenance on my house, so the first thing I usually do is write a list of things I need to fix and what is wrong with them. I had it all written down so I went for a quick nap before I started work. The problem is someone has added a task to the list. I can't start work until I know which one is wrong. They must have inserted it cleverly into the list as I can't figure out which one it is. This is my list in its current state:

• Windows (distortion problem)

• Rats! (huge ones, everywhere!)

• Comet (might land nearby)

• Back garden water tank (Russian)

• Oboe (sounds weird)

• Tags (can't read what they say)

Please tell me which one is wrong so I can begin work. I really don't like the sound of comets landing nearby.

Hint 1

Eveything on this list is written in English. Not all of it was originally in English however.

• It must be Tags, because odd-one-out is one of the tags. – Klyzx May 14 '16 at 14:24
• Lovely piece of lateral thinking there. Unfortunately isn't the answer. – Universalerror May 14 '16 at 14:25

My first thought was this would be related to ...

... computers/programming, but after the previous puzzle and a bit of searching this seems again to be related to WW II.

Windows (distortion problem): Radar countermeasure from WW II.
Rats! (everywhere!): The SOE developed rat bombs during WW II (alternative link with images). This might also refer to the ram air turbine (RAT) which should be present on most aircraft.
Comet (might land nearby): A British tank from WW II. This could be the Messerschmitt Me 163 Komet.
Back garden water tank (Russian): Not quite sure about this one. It might refer to a Soviet amphibious tank from WW II. Wikipedia lists 3 of them (T-37, T-38 and T-40). This might also refer to a Russian tank recovered from an Estonian lake, which was captured by the Germans and had German markings.
Oboe (sounds wierd): A British targeting system from WW II.
Tags (can't read what they say): Transparent Armor Gun Shield, which as far as I can tell was not used during WW II and is therefore the wrong item. This might refer to the Telegraphist Air Gunners.

Not sure about the wrong item yet, but 5 items may be aircraft related.

• A good attempt, though not all for the identified items are quite right. The problems with each thing are a clue as to what they are. – Universalerror May 14 '16 at 13:44
• @Universalerror I changed one item, can you at least tell how many of them are correct? – Sleafar May 14 '16 at 14:40
• You've got all but two of them correct. You may have to broaden what you are looking for with one of them. – Universalerror May 14 '16 at 15:03
• @Universalerror Am I getting closer? – Sleafar May 14 '16 at 19:14
• Looking at all the links I think the answer might be Oboe as it is the only thing not involving Germans per say.. But I can't be so sure and also because that depends on the meaning of rats! – bhaskar Jan 10 at 18:53
