Soldier personal protection equipment (PPE) remains one of the most important and critical requirements to armed forces seeking to minimise casualties and fatalities inflicted across the battlefield.
According to US Department of Defense (DoD) doctrine, PPE "primarily consists of hard armour plates, soft armour plate carrier vests and combat helmets", although it can also include ballistic eye protection; ear and facial protection; as well as solutions capable of protecting limbs and the neck.
According to the US Government Accountability Office (GAO) report, entitled "Personal Protective Equipment" and published on 5th May 2017, PPE systems add "significant bulk and weight to the total load on soldiers and marines, which could impede mobility and hinder combat effectiveness", particularly when considering its utility alongside weapon systems and ammunition loads; communications and electronic devices; food, water and other miscellaneous items.
"The Army is also developing a goal and plan to reduce the weight of hard armour plates by 20 percent by identifying and eliminating excess ballistic protection. In addition, the army and marine corps are pursuing other efforts to reduce the weight of PPE, such as by giving commanders the option to employ varying levels of PPE at their discretion and studying the effects of integrating PPE with overall combat loads," the report added.
Despite ongoing efforts to marginally reduce the weight of plate carrier vests and ceramic plate inserts, the market is now witnessing multiple research and development efforts to proliferate new PPE technology types which could significantly reduce overall weight of PPE by up to 50 per cent, some industry sources have claimed.
Army and Marine Corps service officials described how both force components continued to consider future "updates and redesigned aspects of their respective soft armour vests" aimed at achieving weight savings of up to 40 to 50 percent.
Meanwhile, the army is also considering a series of updates to save weight while increasing ballistic protection of personnel with as yet undisclosed new designs in hard armour plate inserts expected to be revealed in Fiscal Year 2019.
Examples of such next-generation solutions include a joint venture currently being conducted by BAE Systems- Canada and Helios Global Technologies. In July 2017, the pair agreed a Memorandum of Understanding (MoU) aimed at the design and development of liquid body armour technology, which according to programme officials could provide weight savings up to 50 per cent over legacy ceramic solutions.

Moving troops, equipment and supplies onto enemy shores requires very specialist ships. The past century has seen the development of classes of amphibious shipping to meet specific requirements for carrying out opposed landings.
The evolution of amphibious shipping has gone through several key phases, with the first specialist landing vessels with ramps to allow tanks and other vehicles to drive ashore on beaches appearing ahead of the D-Day Landings in World War Two. They became known as landing ship tanks or LST.
Many navies now use a mix of amphibious warfare shipping depending on their nation defence strategy, geography and financial resources available.
LSTS are the most popular amphibious warfare ships because of their simplicity and operational flexibility. As well as amphibious landings, LSTs can be used in humanitarian, peacekeeping or routine logistic support operations.
TCG Bayraktar Class Landing Ship Tanks (LSTs) are amphibious vessels built for the Turkish Navy by Anadolu Deniz _n_aat K_zaklar_ Sanayi ve Ticaret (ANADOLU Shipyard).
These ships are primarily intended for amphibious missions and transportation of troops and equipment, while their secondary missions include humanitarian aid, disaster relief, medical assistance, and transportation.
Cheonwangbong-class LSTs are the next-generation landing ships being built for the Republic of Korea Navy (ROKN) and they succeeded the Go Jun Bong Class ships. The first of class was built by Hanjin Heavy Industries and Construction (HHIC) and launched in September 2013. The fourth vessel of the class will be delivered to the ROKN by the end of 2018.

If there is one thing certain in military aviation it is that despite the onward march of unmanned air systems and space satellite services, there will continue to be a requirement for competent trained pilots for decades ahead and probably for as long as aeroplanes are in the air. Even allowing for an ever increasing reliance on the use of sophisticated flight simulators, including full motion flying and mission training platforms, there can be no substituting in virtual reality the added factors of real flying experience and associated personal risk that comes with preparing for an operational career in the cockpit of a real aircraft.
Because of the extremely high cost of flying the latest front-line combat jets, as well as large military transport and special mission aircraft, on pure training missions is very high, it is inevitable that future pilots will certainly have to spend an increasing proportion of their training time flying simulators of one kind or another, but even on a reduced level the real flying element of preparing new pilots as a part of their flying course must still be maintained and it is in this niche that suitable training aircraft continue to attract the attention of the world"s aerospace manufacturers.
The Yak-130 is a popular advanced trainer, developed in Russia with 110 in service, and supplied to many overseas customer air forces including Algeria, Bangladesh, Belarus, Kazakhstan, Myanmar and Syria. China has developed a copy-cat design, the L-15, and this has been supplied to export customer Zambia. The Yak-30 was the basis for a Russian-Italian joint development and resulted in the Leonardo M-346 which has been developed with Western engines and systems and modified airframe and has achieved export sales beyond Italy to Israel, Poland and Singapore. A feature of the design is its transonic speed capability which gives students hands on experience in handling a fast jet at low supersonic speeds. The best new prospect for the M-346 might be the soon to be announced choice by the United States for a T-38 replacement advanced trainer, the T-X, for which the M-346 is being proposed in an upgraded form as the T-100. It is in competition with a new speculative Boeing/Saab design and the Lockheed Martin T-50A offering in conjunction with Korean Aerospace Industries. Leonardo has been evolving enhanced versions of its M-346 over recent years with the added ability to perform simulated airborne multi-aircraft mission simulations, to compete with advanced versions of the BAE Systems Hawk. Development of the Hawk has not come to an end as BAE has been working with India in proposing a new version with an uprated engine and a new wing design with improved aerodynamics to enhance performance and new avionics and displays. This is aimed at replacing many of the existing Hawks in service around the world since the type first entered service in its Mk 1 version in 1980.
