AN/PVS-4s still in use today are typically upgraded with the AA battery adapter even if they have not been upgraded to a third generation tube. Some AN/PVS-4A models made after 1984 feature an integral AA battery housing that does not require the use of an external AA battery adapter.
WZ-551 is the chassis of the Yi-Tian air defense system, giving the system amphibious capability and added protection. Additionally, a light solid state 3-D passive phased array radar is added to the fire control system, just above the original electro-optical fire control system, providing the ADS with greater surveillance range.
Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...

The U.S. Army Research Laboratory was the technical lead for the Program Manager Soldier Weapons, who worked on the development of the XM25 25 mm individual air burst weapon system. The system was designed to enhance the capability of individual Soldiers to defeat targets in defilade. The XM25 had been utilized in Afghanistan with support from ...
The 120-millimetre (4.7 in) L/44 gun has a length of 5.28 metres (17.3 ft), and the gun system weighs approximately 3,317 kilograms (7,313 lb). By 1990, the L/44 was not considered powerful enough to defeat future Soviet armour, which stimulated an effort by Rheinmetall to develop a better main armament.
