Russia's military capability - the New Look and the Ukraine

With the ongoing invasion of the Ukraine by Russia at the instigation of Russian President, Vladimir Putin, much public commentary has focussed rightly on the unequal scale of advantage that the Russian military possess compared to their Ukrainian counterparts. This comparison is fully justified as the Russian forces both numerically outnumber the Ukrainians and also technologically, but notably not in all forms of weaponry.

Russia has been upgrading its Armed Forces for many years commencing from 2008 not in respect of the Ukraine, but generally due to the wide range of legacy systems from the Soviet era and also the quite poor performance of several parts of the Russian military in the Georgian conflict that year. Following the end of the conflict, then chief of the Russian Armed Forces General Staff, General Nikolai Makarov decided that a massive overhaul was needed and this program became known as the "New Look".

This initiative included a complete change in the Russian Federation Armed Forces military structure that had barely altered since the period of the Soviet Union. The new structure is more versatile, mobile and tailored to operational requirements with no reliance on mass mobilisation that was a feature of the Soviet era. The process of the New Look has been progressing through the State Armament Program 2011-2020 and has been a very long term objective.

The Russians have benefitted from combat experience and systems testing through conflicts in Syria, the Crimea, Georgia and covert operations in eastern Ukraine with the breakaway provinces.  A brief summary of key changes in the Russian military is listed below -

Army/ground forces
  • Smaller combat units have been created termed Battalion Tactical Groups or BTGs, usually a battalion of infantry or armour reinforced with additional armour or infantry units with artillery, air defence and electronic warfare.
  • Tank modernisation has predominantly been upgrading existing T-72 tanks but progress has been slow and new generation battle tanks such as the T-14 and T-15 IFV are still being tested in trials. Armoured personnel carriers and infantry fighting vehicles are mainly legacy vehicles of the past and new-generation equipment is not widely available.
  • Missile and rocket artillery is where significant change has occured (this is a favoured munition of the Russians stretching back to to World War II). A new 500 kilometre-range missile termed the 9K720 Iskander has replaced the 120 km-range Tochka-U. The Iskander can utilize both ballistic and cruise missiles. The existing BM-30 Smerch multiple rockets launcher system (often seen in media film footage) has been modernised  with new systems.
  • There is a strong emphasis on air-portable equipment which is a key reason why the Russians have been focussing on capturing airfields in the Ukraine.
Navy
  • The Navy appears to have undergone the most transformation despite a shipbuilding industry that actually performs well below its declared objectives. Sanctions has played an important role in limiting Russia's ship building industry to deliver effective transformation in naval assets.
  • The two most significant changes are first, the deployment of the 3M14 Kalibr long-range precision land attack cruise missile on both surface vessels and submarines in the fleet. Land based infrastructure is vulnerable to this form of weapon launched from the sea. Second, the deployment of vessels such as the Karakut corvettes and improved Kilo submarines has strengthened Russian fleet assets with the capability to use Kalibr.  
Air force/Aerospace
  • Known for poor performance in Georgia, this part of the Russian Armed Forces has been a focus for improvement. The single role fighter aircraft ( Su-27 Flanker and MiG-29 Fulcrum) have been replaced by multi-role fighter ground attack aircraft such as the Su-35S Flanker M, Su-30SM Flanker H and the SU-34 Fulback. 
  • Air-to air missiles (or AAMs) are being upgraded with improved short, medium and long range AAMs being deployed that can be launched from bomber aircraft. The emphasis is on stand-off, long-range land attack missiles.
  • Tactical air-to-surface missiles mainly with Soviet era designs remain a very slow process with newer designs yet to be deployed in any measurable number.
The Ukraine in comparison has little to no capability in upgrading its weapon systems, developing and/or deploying new ones to provide counterpoints to the Russian inventory.

The United States and Australia - similarities and differences on key issues

As commentators on the politics of the United States have observed, former president Donald Trump continues to exercise considerable influence on the Republican Party (aka the Grand Old Party or GOP) both in terms of policy and the success of potential candidates for elections. His influence also extends to a large proportion of the US public who supported his MAGA (Make America Great Again) slogan. Research by the United States Studies Centre at the University of Sydney published under the title of 'Public Opinion in the Age of Trump' remains relevant due to the polarisation of politics and opinion in the United States.
Using a survey sample size of 1,800 in the United States and 1,820 in Australia, relevant results found these similarities and differences (% shown are in agreement with the statements) -

Global warming and the Earth's axis

                                                                                            Shutterstock
 
Most people would be aware that the Earth's rotational axis is not steady but tends to wobble as the planet is not a perfect unchanging sphere. Due to plate tectonics, erosion, weather masses moving around the surface, large ice masses weighting down sections of land, the poles actually move and this drift averages around 6 centimetres a year. This movement for example drew the North Pole towards Labrador in a Southerly direction.  For compass users, this situation will be familiar due to the adjustment calculation needed for grid to magnetic measurement to compensate for the drift when navigating using maps.

However in 2005 this drift suddenly altered and shifted to an Easterly direction and accelerated corresponding to an increase in the melt occuring in Greenland and Antarctica. Researchers at the University of Texas in Austin found using the GRACE (Gravity Recovery and Climate Experiment) satellites that around 600 gigatonnes of mass was being lost each year by the large glaciers in Greenland, Antarctica and the mountain glaciers. This mount of water being released from the glaciers into the oceans accounted for 90 % of the polar drift since 2005.  In short the planet's tilt was unexpectedly altered due to the effect of climate change.

Ventilation is a key control for limiting transmission of COVID-19

                                                                 Shutterstock
Since March 2021 when the World Health Organisation (WHO)  finally accepted that COVID-19 is an airborne transmitted virus, a stronger focus on ventilation has led to a greater emphasis on air quality, circulation and replacement. While the virus is transported across room spaces in small particles, it can build-up in density in poorly ventilated spaces. But what is the best protection against virus laden aerosols ? How frequently should air in a room space be replaced ?

The basic measure for what constitutes good air is the number of replacements made in an hour and the level of carbon dioxide present (that represents the concentration of exhaled air in a room that comes from other people - and commensurately, the risk of COVID-19).
  
New Scientist (August 2021) published some relevant data from various selected environments around London with surprising results as the chosen locations have an wider application than only that large city in the UK. While the key measure for air quality is the amount of COpresent representing the air breathed out by other people, it is also dependent on there being no other source such as a natural gas cooker or heater. Outdoor air has a concentration of around 410 parts per million (ppm) and below 800 ppm is generally regarded as well ventilated and above 1500 ppm is regarded as critical to exit.

Space, details and highest reading

  • Outdoors:  413 ppm
  • Private car, two people, windows closed: 1,740 ppm
  • Private car, two people, windows open:  413 ppm
  • Private car, two people, non recirculating ventilation on: 413 ppm  
  • Private car, two people recirculating air con on: 1,589 ppm 
  • Bus, lower deck, full doors opening at stops: 724 ppm
  • London train tube: platform between trains: 783 ppm
  • London train tube full carriage standing room only: 1,076 ppm
  • Supermarket, large, empty: 413 ppm
  • Supermarket, small, busy: 1,100 ppm
  • Restaurant, busy by open door: 739 ppm
  • Pub, main bar, full, doors and windows open: 420 ppm
Indoor air quality standards essentially fail to protect from airborne pathogens such as viruses and bacteria leading to a urgent needs for new building and ventilation designs to mitigate airborne risks.

SARS-CoV-2 two years on


It's now two years since SARS-CoV-2 started its move across the world. From 2020, the Johns Hopkins Tracker has charted the data in terms of cases, mortality, jurisdiction and vaccinations. There has always been a level of under-reporting and poor data capture in many countries, nonetheless the staggering number of infections (over 300 million and still counting) and deaths (over 5 million and continuing) is sobering.

The World Health Organisation has warned that the current variant, Omicron should not be considered a 'mild' disease simply due to being less lethal than the Delta variant. It can still be a serious infection as with COVID-19 generally.

Richard Flanagan's book 'Toxic' should be required reading

The Tasmanian salmon industry has long been promoted as ecological, natural, sustainable and providing healthy food consumption for humans. Author, Richard Flanagan comprehensively proves otherwise in his expose on this industry. Published in 2021, the book attracted initial controversy and outrage and highlighted many uncomfortable truths ensnaring well-known companies, Tassal and Huon Aquaculture.  

There have been a few stories, rumours and a small number of comments from scientists that all was not well with the salmon industry in Tasmania. In only 189 pages, Flanagan's book brings all of the evidence and information to bear in an unequivocal condemnation of the aquaculture methods used for salmon farming in the Apple Isle.

To quote from the book " And so we discover that a food product marketed as capable of treating cancer, of miraculously increasing male virility and restoring women's beauty, is in reality a compound of synthetic dye, antibiotics, petrochemical derivatives, the macerated remains of battery hen beaks, skulls, claws. guts and feathers once destined for abattoir waste streams, along with fishmeal made from jeopardised fish stocks stabilised with pesticide also used to stop car tyres cracking that happens to be a carcinogen, and soy meal that has possible links to slave labour and the deforestration of the Amazon and the destruction of the Cerrado and that drives global warming'" [page 72]

It is no small claim to compare the importance of this book to the seminal work by Rachel Carlson 'Silent Spring' which has been a foundation block for environmental science for decades. 

Of note, Australian mining magnate and known environmentalist, Andrew Forrest attempted to take over Huon Aquaculture in 2021 but was beaten by Brazil-based international meat processor giant JBS in November 2021. It remains to be seen whether JBS cleans up Huon's operations in Tasmania or not.

2022 - the COVID-19 period continues

                                                                                               (c) Sentinel Owl

A new year has commenced and brings the continuing pandemic with it. The new variant of COVID-19 (SARS-CoV-2), Omicron, is considered by health professionals to be two to three times more infectious than its predecessors. This is thought to be due to changes in the spike protein and its immune evasion properties in comparison to previous COVID infections. 

Of note, no longer will the basic surgical mask or the cloth masks provide any protection (if these ever did) but rather it must be the P2/N95 level of mask which must be correctly fitted so that air is drawn through the mask rather than from any gaps around the face. The benefit of using face masks to prevent transmission of the virus has been demonstrated across the world and will need to remain a basic part of the community's attire for the immediate future.
