The eight-wheeled (8x8) Stryker combat light armored vehicle was adopted by the US Army in 2002 to provide a comparatively rapidly deployable contingency force with armor protection, tactical mobility, and heavy firepower, as well as advanced command, control communications, computer, intelligence, surveillance, and reconnaissance (C4ISR) capabilities. Covering the first new US Army release since the M1 Abrams MBT, this book details the conception, ongoing development and deployment of one of the most highly anticipated new AFVs in recent years, including its service in Iraq and the ensuing controversy surrounding the Stryker's varying successes.

Partiendo de la nada y con una aportación alemana e italiana poco valiosa - militarmente hablando-, el Ejército Nacional llegó a organizar dos unidades de carros de combate. La captura de carros y blindados sovieticos, provenientes del Ejercito Republicano, constituyo la principal fuente de materia prima para dichas unidades.
Las colecciones de armas y armaduras constituyen una parte fundamental pero poco conocida del legado cultural europeo, desde las grandes armerías dinásticas o los museos militares a las colecciones publicas o privadas. En su mayor parte son custodiadas en todo el continente por un reducido numero de instituciones entre las que destacan los principales conjuntos dinasticos. Por ello la presentacion de un nuevo conjunto poco conocido constituye por si misma una novedad destacable. En este caso se trata de las armaduras renacentistas y barrocas de Santa Maria de Ocaña, en la provincia de Toledo. En ellas llama la atencion que, a pesar del reducido numero de elementos del conjunto, compuesto por apenas diez armaduras heterogeneas, se hallan piezas destacadas por su calidad, tipologia o la relevancia de sus autores. Entre estos ultimos se encuentran armeros como los alemanes Desiderius Helmschmid de Augsburgo o Wolfgang Grosschedel de Landshut, que trabajaron al servicio del emperador Carlos V y de Felipe II. La utilizacion de estas armaduras hasta la actualidad con fines liturgicos durante la Semana Santa es uno de los rasgos mas destacados de este grupo. Por ello se relacionan con las de las numerosas hermandades que en la geografia española continuan formando guardias pretorianas acompañando a la imagen de Jesus ...
The Chance Vought F7U Cutlass was ahead of its time In 1948 when it first flew it could hardly have been more exotic or state of the art a tail less fighter to be powered by two afterburning jet engines It was not only to be carrier based but also climb quicker and be faster than the Air Force s new swept wing North American F 86 Sabre Developmental problems resulted in it taking too long to reach operational squadrons which partly accounts for its relatively unsuccessful career The Cutlass was designed too soon to benefit from the discovery of the area rule which doomed it to transonic performance in level flight Similarly its lack of a horizontal tail was intended in part to address the transonic pitch control difficulties being encountered at the time but they proved to be avoidable with one Unfortunately no horizontal tail resulted in it not only being radical in appearance but also having challenging handling qualities at approach speed The F7U 3 s service introduction was also accomplished before the Navy perfected a rigorous process for transitioning pilots to new airplanes particularly important in the case of the Cutlass and its unusual handling qualities one of which resulted in a rare aeronautical phenomenon the post stall gyration It was
