Could this just be an attempt to proof the fuel tank against small arms, shrapnel and small drone dropped munitions? Or just to reduce the trucks IR signature? Wood is a very effective barrier, insulator even when used in small planks.

All looks a bit desperate though.

In fairness, many countries try to disguise their fuels vehicles as something less noticeable. The French have a long history of trying to make their more tactical fuels vehicles indistinguishable from other military cargo vehicles by putting a soft top over the fuel equipment.

​​​​​​The most surprising thing, given how important fuel is in the grand scheme of things, is that more countries don't do it.

Small arms fire penetrates 60cm of fresh wood (eg AK47 from the distance of 150m). Those thin planks won't help against what ever is in the air over there.

Nope, made to look like it is carrying logs.

Almost all the IR is probably going to come from the hot engine and warm cab I think. The fuel in the tanker will be closer to the air temperature I think.

Any other Brits see the programme on BBC2 last night? Interesting to see the Uke volunteers in action

Yes, I mentioned it over on the other thread earlier: Russia, Ukraine, and possible unpleasantries

Showed the human side of the work of the volunteers pretty well, I thought. Interesting to see the way they were getting lots of intel from Ukrainians inside the occupied territories, too.

Rotor flicker was an issue but generally minimised by not using high AoB in turns.
The ZD Notch was to do with maintaining the same relative distance from the radar/seeker head so it saw no relative movement when looking at the aircraft fuselage.

Probably irrelevant to modern weapons and radar.

Blue Vixen in initial trials (BAC111) had trouble with motorway traffic dopplers at c70kts. That was filtered out but they then found similar probs at c140kts. Yep, you guessed it - the tops of the tyres (tires for our US cousins). Bit cleverer than Blue Fox!

When West Raynham was a Bloodhound site, we were tasked with simulated attacks in our mighty tin triangle. Running towards it at low level and 300KIAS, as soon as we heard a locked indication on the RWR we would break at 60 AoB, then reverse to beam the signal until it broke doppler lock. Then another 60 AoB turn back onto the bomb steer to run in again and repeat as necessary until we reached the minimum engagement range before simulated lay down weapon release. That took a fair bit of coordination; one pilot hauling it around, the other calling estimated AoB values to achieve a constant radius arc around the target, the AEO calling RWR indications with pilots listening to RWR audio, nav radar keeping the target in sight and the nav plotter confirming position. We succeeded a couple of times, but it was quite fatiguing on both the aeroplane and crew. Later attempts were thwarted after the Bloodhound radars were upgraded and zero doppler attacks no longer worked as well. Great fun though!

Lyneham radar would often get confused by GWR trains - but on one occasion the low level radar contact 'in your vicinty' was indeed low level! A tractor with crop spraying booms looking to all intents and purposes on radar like a manoeuvring aircraft.

What has all of this to do with Ukraine? Just asking.

In all fairness Nutloose, there are many sad things going on in england right now being blamed on the situation in Ukraine.

Things which also have little to do with Ukraine !!

It actually increases the intelligence of Russian vehicles.

We all know the average russian soldier is as thick as two short planks. Therefore strapping a number of short planks to a vehicle actually increases the intelligence of that vehicle, therefore mitigating to some extent against the relative lack of intelligence of the Russian Soldiers.

​​​​​​​Apparently.
