Send Channel migrant boats to Ukraine to help war effort, Government urged

MissionUkraine says poor quality boats still useful to troops because marine engineers in war zone are able to refurbish them



" Boats used by migrants to cross the Channel to the UK should be sent to Ukraine to help the war effort, a volunteer organisation has told the Government.

Since October, British and Ukrainian volunteers have delivered 15 inflatable dinghies and rigid inflatable boats to soldiers fighting along the Dnipro River.

The small boats, which were in relatively poor condition, were driven from the UK to the south of Ukraine, where they were refurbished. This included the installation of new engines and painting the vessels khaki.

They have provided a lifeline to the Ukrainian soldiers holding three established bridgeheads on the occupied eastern side of the river, by carrying vital supplies and evacuating wounded soldiers."

This seems an excellent idea. I have contacted Mission Ukraine to ask if they have an efffective e-mail address to contact Border Force to urge them to review their decision and will add it to this post as soon as I receive a reply.
I suggested that on here last year lol. Good to see someone is thinking along the same lines.

You just have to get them when they flash! ​​​​​​​

If these are kosher [IF] it seems probable that the external garment skin is held at ambient air temp.
Meanwhile, inside the suit, the soldier is moving, grunting, breaking wind, lifting, lining up a weapon, frightened ............ and his heat output has no escape.

​​​​​​​Cooked Ivan, anybody?

Anyone any idea how these are supposed to work ? It is extremely difficult in the normal world to prevent significant heat-loss when there is a major temperature gradient and the most efffective material ( Aerogel - ) is very expensive and certainly not thin enough to be made into usable clothing. What kind of temperature difference is needed to get a reasonable identification of a human body ?

Magnetic strips for closing, memory bands to encourage the closed position? The feet still show up, so possibly battery-powered fans to blow heated air downwards(?).

Remember that you're not trying to block heat loss, you're just trying to prevent emission of IR radiation. Heat transfers by conduction, convection and radiation, most of it for a body in air by hotter air convecting away from the body but that is not what IR cameras are detecting.

Heavens above! Ruzzia can't even supply its troops with boots, socks, sleeping bags, cold weather clothing or basic First Aid - even with weapons. What chance is there of providing them with sufficient amounts of high-tech IR proof suits to make any difference at all?

Sort of looks like they are wrapping themselves in a mylar 'space' blanket, which will work for a short time, but the heat has to go somewhere eventually.

Taliban worked this out. Seems to have taken the Russians a lot longer.

that's not IR proof demo, thats thermal imaging demo. You can do that by waving two sleeping mattresses in front of a person, those work very well if you want to hide your thermal foot print, even below freezing temperatures.

Humble apologies, auto correct sucks.

Or someone with a vested interest doing the odds on:

  • a 9x25mm Makarov
  • polonium flavouring
These seem to have some prevalence with the dicktater of Fowlty Towers. Seems a shame to spoil the tune. Lord Farquard is starting to peer into the abyss, 400K #200s etc, the growing dive attractions in the Black Sea, the demonstrated prowess of Russian armaments capability, the strength of his economy, (eggs, lada's etc) and the lack of heat, water, electricity for a growing number of Russian "voters"... It appears that Count d'Money not only appreciates KJU's technical mastery and munitions quality, (3 out of 4 dud mortars still is 1 out of 4 bits that go bang) he appears to be well on the way to emulating NOK isolation, productivity, legal system, and generally their position in the global standard of living and ranking in places where one may wish to vacation or immigrate to.

The thermal image masking is a partial solution, it is not a total solution, it can be defeated quite simply... I would think anyone relying on such technology would be well advised to not do so for very long. In my former life chasing Soviet ballistic submarines some surprising paradoxes emerged, and they are applicable concepts to this form of masking.

Many fabrics and fabric cleaners glow in the UV range. It would be quite amusing if the Orcs could be found by that means. By hunting submarines, was it a case of looking for what wasn't there ? Just a hunch.

As far as I understand and have been able to confirm, these are directly linked as far as humans are concerned, so to prevent IR emission, you have to prevent heat emission (and detection ).
