The Royal Thai Navy (RTN) received six Special Operations Craft – Riverine (SOC-R) on 18 March to replace aging Patrol Boat Riverine (PBR).
These 10m-long SOC-R boats were built by Marsun, the Thai dockyard that also built the first three M10 Mk I SOC-Rs in 2012. These latest M10 Mk II boats are designed to operate along inland waterways and in coastal areas, chiefly to support special operations.
Propulsion comes from two 420hp engines with waterjets offering maximum speeds of 40+kt. They carry five crewmen and eight troops. The heaviest possible armament consists of three .50-cal machine guns.
These new SOC-Rs of the Riverine Squadron will operate in inland and boundary waterways like the Mekong River and Golden Triangle.
Their missions are to keep the peace, prevent illegal immigration, human trafficking, drug smuggling or any actions that harm homeland security. The SOC-Rs also provide fire support in combat situations.
Additionally, the boats will be used in humanitarian relief missions and to protect the royal family and VIPs.
The RTN needs more than 40 SOC-Rs to replace the Riverine Squadron’s 39 aging PBRs, some of which are more than 30 years old. All will be locally built.
Russia is planning to modernize its 150 T-72 main battle tanks (MBT) to the T-72B3M version also called T-72B4. According to Russian military engineers, the upgraded T-72 MBT will be comparable to the more advanced T-90, but with much lower costs.

Currently, Russian armed forces use a wide range of T-72 MBT variants. The T-72 is a russian made main battle tank that entered production in 1970. It is a further development of the T-62 with some features of the T-64A (upgraded version of basic T-64) and has been further developed as the T-90.
Russia will spend 2.5 billion rubles ($37 million) to upgrade 150 T-72Bs to the advanced B3M standard, Uralvagonzavod deputy director Alexey Zharich told the Russian newspaper Izvestia.
The T-72B3M (T-72B4) will be upgraded with lot of new components including the new cannon 2A46M5 125-mm smoothbore gun as well as the new Sosna-U sighting system paired with the 1A40-4 fire-control system. The tank will also receive a new ballistic computer to increase accuracy.
The upgraded T-72B3 were first seen during rehearsal for the Victory Day Parade which has increased protection than the standard T-72B3 featuring new add-on explosive reactive armor package, which covers rear part of the turret. This tank is also fitted with cage armor, which covers rear parts of the hull and turret and improved side skirts.

The most notable upgrade is the stabilized, panoramic, independent commander’s PK PAN sight with integrated thermal viewer, thought to have similar specifications to the Sosna-U. This gives the tank the ability to engage targets in the “hunter-killer” mode. Source wikipedia.org

The tanks will also get the new Relikt explosive reactive armor. It will replace the old Kontakt-5 system and is expected to be two times more effective.
“Classic” ERA from the USSR and Russia 4S22 (Kontakt-5)
It’s good to start describing “Nozh” with a point of reference first – for example heavy reactive armor types designed in the USSR/Russia, 4S22 (Kontakt-5) and 4S23 (Relikt). The overall working principle of every classic ERA is similar – it’s based on movement of metal elements of the ERA cassette caused by an explosion of reactive elements , this inflicts side stress disrupting the cumulative jet from a HEAT round or bending (optimally breaking) of an incoming KE penetrator. This overall principle is realized by different cassette’s structure. First, let’s look how Kontakt-5 ERA provides protection for Object 188 (T-90S tank).
4S22 Kontakt-5 scheme. Dark blue – external hardened metal
plate, violet – elements preventing the explosive inserts from moving, light
green – explosive inserts, light blue – cassette’s back plate and mounting
points. The explosive inserts are shown below the scheme. All pictures belong

Supremacy of Soviet armor?
The introduction of heavy Kontakt-5 ERA in 1987 caused a gap between the capabilities of NATO’s rounds and the armor of Soviet tanks. From theoretical point of view APFSDS and tandem HEAT warheads capable of penetrating heavy ERA were introduced in 1992-1994 thus creating an almost 6 year disproportion between the Soviet “shield” and the NATO’s “sword”. Another fact worth noting is that the basic armor of Soviet tanks was already largely immune to APFSDS rounds, majority of RPG’s and some ATGM’s warheads. A good example is the basic armor of the hull and turret of the export version of Object 478B (T-80UD from 1991) including both steel and ceramic elements it is over 620 mm RHA vs APFSDS and over700 mm RHA vs HEAT. By adding Kontakt-5 ERA the protection level is further increased – especially against HEAT warheads. Similar high protection is for T-72B model 1989 when the sum of only passive hull armor elements gives over 600 mm RHA vs APFSDS.
Presented situation was theoretically very dangerous for western AT rounds but it was lowered by few factors – rather large weak zones in the frontal armor and not thick enough coverage by ERA cassettes. In reality every tank has various weak zones which can be penetrated by older ammo. In case of T-72 family these are: gun mantled, gun mounting area, coaxial MG, turret roof, commander’s observation copula, turret ring and the lower hull glacis.
These weak zones are shown in a résumé of an article printed in the internal bulletin
of the Armored Forces of the USSR. The article states about advantages of tanks
with welded turrets in terms of better crew survivability. What’s important is
that T-72B (Object 184) was used as a reference point and its weak zones were
T-72B weak zones
The areas marked in red were considered weak zones and could be
penetrated by 3BM26 APFSDS which was introduced in 1984 and penetrates 380-410
mm RHA at 2000 m for 90 degree sloped target. The marked areas were penetrated
by this projectile from:
– driver’s hatch – 1700 m,
– turret roof – 3700 m,
– commander’s copula – 3900 m,
– gun mantled, gun mounting area and coaxial MG – 1650 m

Relikt explosive reactive armor
Relikt consist of single explosive tile, sandwiched between 2 plates. At event of hit, explosive detonates and “push” plates in opposite directions. And thats all, there is no second explosive charge. IIRC NII Stali noted that there is a sort of damper layer on armor itself (between ERA main part and armor plate of a tank), to soften up a force from second (“inner”) plate hit. @sturgeonshouse.ipbhost.com
New Relikt explosive reactive armor @sturgeonshouse.ipbhost.com
Nozh offers slightly higher protection than Kontakt-5 against some warheads simply because K-5 module have 0.5 kg of explosives, while one block of Nozh is filled with ~2 kg of explosives. Relikt also have about same amount of explosive filler, but Nozh is mounted directly on tank armor, while Relkit is mounted at some distance, with second inner plate and damper mounted on armor plate to protect it from damage by ERA detonation.

Furthermore, the upgraded version will be powered with the new V-92S2F engine and deliver 1,130 hp. It will replace the old 780-hp diesel engine. The new engine is paired with an automatic transmission system and improved drivetrain to improve the tank’s mobility. Source armyrecognition.com

V-92S2F diesel engine was specially designed for installation on the upgraded and new serial tanks T-72B3. It has a power of 1130 hp.
The V-92S2F is the result of a deep modernization of the V-92C2 engine, with which it has a high level of unification: it has the same overall dimensions and is installed in the power compartment of the main battle tank without any modifications of the hull.
But in comparison with the B-92S2, it has a more powerful crankcase, crankshaft, conrod-piston group, improved turbocharger, exhaust system and cooling system. The heads of the cylinder block are cast from a heat resistant aluminum alloy. The fuel system provides high efficiency and has a power limiting mechanism that reduces the load on the diesel engine when the temperature extremes are reached.
The beginning of the mass production of the B-92S2F diesel engine was announced in November 2017. Source army-guide.com
Основные новинки представленного танка заключаются в двигателе (1160 л.с. с автоматом переключения передач), новом панорамном прицеле командира с лазерным дальномером (ВОМЗ), установке телевизионной камеры заднего обзора на кормовом листе корпуса танка и ряде других усовершенствований. – The main novelties introduced by the tank are in the engine (1160 HP with automatic gear), new panoramic Commander’s sight with laser rangefinder (VOMZ), installing rearview camera on the tank hull fitted sheet and a number of other improvements.
Решение весьма неудачное, т.к. полностью препятствует усилению бортов динамической защитой – Log an unditching beam placed on the right side (on-the-go tank) in connection with the installation of the rear view camera. The decision is very unfortunate, because it prevents the strengthening boards dynamic protection.
Установка ДЗ на башне аналогична Т-72Б3. У наводчика установлен многоканальный прицел «Сосна-У» разработанный белорусским ОАО «пеленг».
