In November 2021, defence analysts noticed that Russian tanks were sporting strange cages on top of their turrets.
Unmistakably, this was “slat armour”, or cage armour, designed to deflect incoming anti-tank missiles or shells, knocking them off trajectory, crushing their fuses before they hit the tank’s main armour or detonating them before they reach the tank.
Evidently, the armour has not been effective, as shown by conflict monitors who have identified hundreds of destroyed Russian tanks, many with the cages lying idly beside the wrecks.
For small missile and rocket-propelled grenade warheads, analysts say this kind of cage armour has a decent chance of success and is used by militaries the world over.
But why was it placed on the tank’s roof?
The type of shoulder-launched weapons that cage armour can stop, such as the rocket-propelled grenade launcher (RPG) are typically fired horizontally at the front, back or sides of a tank.
Some modern anti-tank missiles supplied to Ukraine, such as the Javelin and Next Generation Light Anti-Tank Weapon (NLAW) are designed to explode above a tank's thin roof armour – leading some observers to think the cages were a haphazard DIY defence against this "top attack".
But this might not be the case. In December, one Russian defence analyst had observed how cage armour would not stop a modern anti-tank missile.
Dmitry Litovkin told Russia's Tass news agency that slat armour was "less effective against tandem-charge high-explosive munitions", or weapons that have two explosive charges, one to blast away defensive armour, and a bigger, main charge.
That is exactly how Javelin and NLAW missiles work, suggesting the Russians might have had another defence in mind, possibly drones with small missile warheads attacking from above, or RPGs being fired from rooftops in urban battles, a problem Russia encountered in Chechnya.
On a Russian T-72 tank, frontal armour is the equivalent of about 500mm of steel, but on the roof it is far less – as little as 30mm.
Top attack weapons
Modern anti-tank weapons such as the Javelin, which was already in service in Ukraine before the invasion, have what is called a “top attack” mode precisely for this reason – targeting thin top turret armour.
A number of analysts recently explained that the problem with these cages is that a lot of anti-tank weapons in use in Ukraine do not have a fuse in the nose – negating one of the cage’s protective methods of crushing the fuse.
The principle behind cage armour dates back to the Second World War when German tanks were fitted with “spaced armour” to destroy or deflect incoming anti-tank shells.
Arms research service Calibre Obscura describes the usual circumstances where the armour can work.
“Essentially the main thing with these cages is that they seek to replicate slat, or cage armour, which has genuine effectiveness when it comes to armoured vehicles, as it has the ability to disrupt some (but not all) RPG variants, such as the PG-7V and reduce the likelihood of a successful hit,” according to Calibre Obscura.
US forces briefly experimented with cage armour during the Vietnam war but decided it limited vehicle mobility because of its bulk and weight.
Lightweight cage armour variants, including aluminium armour, were later used by coalition forces in Iraq and Afghanistan.
Why the cages can't stop Javelins
In the late 1980s, modern anti-tank weapons were developed to target tank turret roofs.
Some Russian tanks subsequently have explosive armour on their roofs to deflect missiles, but modern anti-tank weapons have a "tandem charge" that explodes to detonate the armour, before the more powerful main warhead detonates.
For the main warhead, missiles such as the Javelin and the NLAW use what is known as a shaped explosive charge which concentrates explosive power to defeat armour.
Test videos of American Tow missiles in top attack mode against Soviet era T-72 tanks show the missile exploding far above the tank’s roof – well above the height of any cage.
Sensors in the missile know exactly when it is flying over the target.
The Tow missile explodes several metres above the T-72, causing a catastrophic explosion. Similarly, the top attack mode of the NLAW and the Javelin have a proximity fuse, meaning that it does not have to make contact with cage armour before detonating.
In both cases, a jet of superheated metal is directed into the tank – capable of penetrating hundreds of millimetres of steel. Any cage therefore, would be rendered useless.
Calibre Obscura believes that even in cases where the slat armour could be useful, perhaps against small "kamikaze drones" or small munitions fired or dropped from drones, the DIY nature of the Russian cages could still be a fatal flaw.
Quality engineering "does not apply to the 'cope cage'," the group wrote, using a popular online term for the armour.
"The 'grill' appears to be less dense than proper cage armour and constructed from random household materials in some cases."
The US recently sent Ukraine Switchblade 600 loitering munitions, or "kamikaze drones", which can be used to attack the roofs of tanks, although there is no evidence they have been used in the conflict so far.

The five pillars of Islam
Background: Chemical Weapons
Ten tax points to be aware of in 2026
1. Domestic VAT refund amendments: request your refund within five years
If a business does not apply for the refund on time, they lose their credit.
2. E-invoicing in the UAE
Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption.
3. More tax audits
Tax authorities are increasingly using data already available across multiple filings to identify audit risks.
4. More beneficial VAT and excise tax penalty regime
Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.
5. Greater emphasis on statutory audit
There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.
6. Further transfer pricing enforcement
Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes.
7. Limited time periods for audits
Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion.
8. Pillar 2 implementation
Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.
9. Reduced compliance obligations for imported goods and services
Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations.
10. Substance and CbC reporting focus
Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.

UK's plans to cut net migration
Under the UK government’s proposals, migrants will have to spend 10 years in the UK before being able to apply for citizenship.
Skilled worker visas will require a university degree, and there will be tighter restrictions on recruitment for jobs with skills shortages.
But what are described as "high-contributing" individuals such as doctors and nurses could be fast-tracked through the system.
Language requirements will be increased for all immigration routes to ensure a higher level of English.
Rules will also be laid out for adult dependants, meaning they will have to demonstrate a basic understanding of the language.
The plans also call for stricter tests for colleges and universities offering places to foreign students and a reduction in the time graduates can remain in the UK after their studies from two years to 18 months.

What is the definition of an SME?
SMEs in the UAE are defined by the number of employees, annual turnover and sector. For example, a “small company” in the services industry has six to 50 employees with a turnover of more than Dh2 million up to Dh20m, while in the manufacturing industry the requirements are 10 to 100 employees with a turnover of more than Dh3m up to Dh50m, according to Dubai SME, an agency of the Department of Economic Development.
A “medium-sized company” can either have staff of 51 to 200 employees or 101 to 250 employees, and a turnover less than or equal to Dh200m or Dh250m, again depending on whether the business is in the trading, manufacturing or services sectors.
Red flags
- Promises of high, fixed or 'guaranteed' returns.
- Unregulated structured products or complex investments often used to bypass traditional safeguards.
- Lack of clear information, vague language, no access to audited financials.
- Overseas companies targeting investors in other jurisdictions - this can make legal recovery difficult.
- Hard-selling tactics - creating urgency, offering 'exclusive' deals.
