They are systems that are cumbersome for foot transportation and must be transported by technical means as wheeled frames and/or vehicles, aircrafts, etc. They comprise mortars, artillery systems, and rocket launchers.
From tissue paper screens to radar screens: some episodes in the development of ballistic testing methods
Published in The International Journal for the History of Engineering & Technology, 2021
Initially, the Shoeburyness ranges (‘Old Ranges’) were mainly for training purposes with a permanent gunnery school added from 1859, alongside a garrison. However this was a period of extensive innovation in all areas of engineering, not least that relating to military activities, since there seems to have been no time from 1800 to 1921 when the United Kingdom was not at war with someone somewhere.4 The Royal Artillery was responsible for facilitating the testing of newly-invented weapons offered for use by their inventors, for both the army and the Royal Navy, as well as ‘proofing’ weapons, explosives and ammunition coming from manufacturers. Proofing is the testing of statistically-selected samples under controlled conditions to provide quality assurance, as we would term it today.
Inspired by British inventions: Joseph von Baader (1763–1835) — a Bavarian engineer fighting a losing battle

The young smith was the 19-years old Georg von Reichenbach, the son of a master cannon-borer and artillery lieutenant in Mannheim. Young Reichenbach was educated at a Mannheim military school and, according to an official document from May 1791, sent with a grant from the Mannheim military budget to England ‘in order to bring his mechanical art to perfection’.17 From the available archival material it is not clear whether the order of a steam engine was merely a pretense for industrial espionage. Boulton seems to have entertained suspicion from the very beginning in view of earlier experience with foreign visitors.18 When Baader and Reichenbach arrived at Soho, they were coldly received, as Reichenbach recorded in his diary on July 10th, 1791:
Case study on applying sequential analyses in operational testing

To motivate the use of sequential methods, we use the AN/TPQ-53 Counterfire Radar (Q-53) as a case study. Mortar, rocket, and artillery fire posed a significant threat to U.S. forces in Afghanistan and Iraq and will likely remain a significant threat to ground troops in future conflicts. The Q-53 (Figure 1) is a ground-based radar designed to detect incoming mortar, rocket, and artillery projectiles; predict impact locations; and locate the threats geographically. Threat location information allows U.S. forces to return fire, and impact location information also can be used to warn U.S. troops. The Army conducted the initial operational test and evaluation (IOT&E) of the Q-53 in June 2015.
