This article analyses the main challenges and future prospects of creating United Nations (UN) rapid reaction mechanisms, particularly in the light of past attempts and current discussions about a “UN Vanguard Force” in the wake of the High-Level Panel on Peace Operations report. The article reviews major initiatives (in particular lessons from the Standby High Readiness Brigade for UN Operations) and assesses the main achievements, failures, and challenges related to past UN-led rapid reaction mechanisms. In line with the overall aim of this special forum, the article highlights the future potentials and institutional, operational, financial, and political challenges that need to be overcome in order to design and create a pragmatic and effective rapid reaction tool at the disposal of the UN. 相似文献

This paper introduces the Duke of Richmond’s Muskets and their precursors as made by Henry Nock and others. It particularly explores the development pathway for Nock’s Screwless locks by examining the production variants, the known prototype and experimental versions and in particular the prototype breech loading muskets. There are now known to be three breech loading prototypes, two very similar guns with locks marked by Henry Nock and a similar gun that appears by comparison to locks known to be by Walter Dick to have a lock made by Dick. This examination indicates that Nock was likely to have been instructed to make the production lock smaller than the prototype and that a key design step that enabled this was the use of a small double-ended mainspring linked to the cock and actuating the steel (frizzen) via a lever as developed by Dick. 相似文献
