Is Ukraine about to have a war?

I missed that. Took it at face value as looked green.

I counted some 20ish mines spread evenly on the deck of that BMP. That"s some 100kg of TNT in an environment where one of the main entertainment of Ukrainian drone drivers is dropping mortar rounds on RuZZians...

I just can't get my head around why on earth they'd transport mines like that, tied down all across the vehicle. I'd prefer them in their boxes as well, at least it would allow two men to quickly create a blockade but now they'd have to untie them separately.

I must admit, I feel no dismay at the hazardous practices on display. I would much prefer Russian forces personnel to annihilate themselves than any Ukrainian, military or civilian.

I am aware that war brings an awful, bloody loss of life. I have been mildly surprised at how fast I started to negate the value of the Russian forces' lives in this war. So be it. The sooner this is over, the better.

Recriminations are continuing in Russia about the disastrous Ukrainian HIMARS strike on mobilised soldiers in Makiivka. The Russian ministry of defence's statement blaming the mobilised themselves for giving away their location is being heavily criticised as a cover-up. ⬇️

«The air defense system worked in the Rostov region on Tuesday evening to eliminate a small object in the shape of a sphere» - the governor said. I wonder what kind of object it could be...

Guide for Russian partisans: - Buy big balloons, - Buy helium - Under the cover of night, launch helium balloons into the sky - Watch as Russian stock of air defense missiles slowly dries up

metallic ones.. for best radar return, and with a nice easterly wind.. could be onto something. after a day or two, mix in a drone hanging from a balloon..

Though would work both ways..

One wonders what window would do to modern air defences?

RECORD cold heading for Moscow

while most of europe has experienced a warm december and new year..https://www.bbc.co.uk/weather/524901

so much for lights going out. all that comedy propaganda. -24'c ...offt

I don't know but a balloon carrying a corner reflector might well look a bit like a small drone, as long as there's a bit of wind in the right direction. I remember making some ad hoc corner reflectors from bits of cardboard covered with aluminium foil years ago. They worked just fine and gave a pretty solid return.

From everything I've read, the computers are usually set to eliminate contacts below a certain speed/size to avoid bird alerts (and balloons )

For surveillance and air traffic type radars that's true, there's a Doppler limit set to ignore slow moving stuff to get rid of clutter. However, drones can fly very slowly and I doubt the plastic propellers give much of a return. My guess is that an air defence radar has to have the ability to detect a target with very low, even no, relative motion with respect to the radar.

What about buying and lobbing some unguided model rockets at them, this one cost 20K and climbed to 70 thousand plus and mach 2 ?

The old Met radio sonde people derived some great spectaculars ..... the big balloons had a decent payload, reflector was standard issue, fuses and explosives easily improvised ....so give low buoyancy, low rate of climb, long fuse and the right wind direction. sirens every night in Moscow, cost peanuts.
I might even be pursuaded to come out of retirement.

Perhaps use your store of dried seaweed to start a fire or three.

Ah the old Zero Doppler (or ZD) Notch - a valid heli tactic in the 80's against ground and air threats

Don't forget the chicken bones - rubbed together briskly they could be a source of ignition

In articles reporting the Ukrainian comments on this attack, I read that they (Ukr ) said that the attack destroyed "10 units of enemy equipment". Has anyone any idea what that referred to ?

There were uncamouflaged vehicles on the site.

It’s clear now that ukr has switched its targeting from ammo to troops. more and more troop concentrations are being hit driving up the numbers of russian dead. this morning they hit another one. if ukr is saying that 720 (aprox) then triple it to get the true KIA/MIA number

Bugger all - and that’s been true since the 1970s.

MTI, Doppler MTI*plus many other forms of signal processing will identify and remove such clutter - including bird formations, heavy cloud, Met balloons etc.

Same processing used on airborne radars to remove ground clutter, motorway traffic etc.

* And with a digital 3D radar they can be applied in thousands of discrete height layered squares to compensate for differing wind speeds and directions etc.
