Luftförsvar för stärkt kustförsvar : En studie om burna Lv-robotsystem i amfibiebataljonen

Holmberg, Andreas January 2018 (has links)
The traditional landings with large warships near the coastline have been replaced by means of vessels moving beyond the horizon from the coast where the landing will take place. The old landing crafts have been replaced by transport helicopters and close air support, a threat that the amphibious battalion lacks resources to meet. The Swedish Armed Forces faces a possible acquisition of MANPADS and therefore the main purpose with this study was to examine the systems: FIM-92 Stinger RMP, Mistral and RBS70 NG, in order to assess which one of them who had the greatest potential to be effective when used by the amphibious battalion in a coastal defense operation. The study was conducted as a multiple criteria decision analysis, based on the concept of military utility. The result indicated that the RBS70 NG was the system that best met the requirements and demonstrated the greatest potential to be military efficient, although Mistral with minor exceptions fulfilled the requirements. As the study was delimited to a theoretical study based on three specific scenarios, further studies are recommended with simulations, as well as field trials before the result can be given a higher validity. The result, however, already helps us to understand how MANPADS contributes with military utility in coastal defense operations. / De traditionella landstigningarna med stora fartyg uppträdandes kustnära har ersatts med metoder innebärandes att fartygen rör sig bortom horisonten från den kust där landsättningen/landstigningen ska ske. De gamla landstigningsbåtarna har i hög grad ersatts med helikoptrar som understödda av attackhelikoptrar och flygplan utgör den nya dimensionerande hotbilden. En hotbild som amfibiebataljonen saknar resurser för att möta. Då Försvarsmakten står inför en eventuell anskaffning av ett buret luftvärnssystem till amfibiebataljonen har denna undersöknings främsta syfte varit att bedöma vilket av systemen FIM-92 Stinger RMP, Mistral eller RBS70 NG som uppvisat störst potential att vara militärt effektivt när de nyttjas av en amfibiebataljon i kustförsvarsoperationer. Undersökningen genomfördes som en komparativ analys med multimålmetod och tre olika typfall som grund. Jämförelsen tog sin utgångspunkt kring teoribildningen om militär nytta och då mer specifikt militär effektivitet. Resultatet indikerade att RBS70 NG var det system som bäst mötte amfibiebataljonens krav och därmed uppvisade störst potential att vara militärt effektivt, även om Mistral med enstaka undantag också uppfyllde kraven till synes utan begränsningar. Då studien avgränsats till en teoretisk jämförelse i tre specifika typfall, rekommenderas fortsatta studier med såväl simuleringar som praktiska prov innan resultatet kan ges en högre validitet. Resultatet bidrar däremot redan nu till en förståelse för vad som ökar den militära effektivitetenvid genomförande av kustförsvarsoperationer.

"The War Comes First": Lt. Col. Francis Carroll Grevemberg and the Development of a World War II Antiaircraft Artillery Officer

Janous, Robert 14 May 2010 (has links)
This thesis deals with the life and career and intimate life of Francis Carroll Grevemberg, an antiaircraft World War II officer from New Orleans, Louisiana. Grevemberg joined the Louisiana National Guard in 1932 and began his military career in the midst of the Great Depression. In the reorganization of the U.S. Army before World War II, the War Department transformed Grevemberg's cavalry regiment into a coastal artillery battalion with antiaircraft capability. During World War II, Grevemberg saw continuous action in the North Africa, Italy and Southern France. He regularly wrote letters from battlefields to his wife Dorothy. These letters provide a important window into a young officer's feelings, thoughts and affection in the unfolding of World War II. They are documents of a soldier's emotional release during times of crises. Lt. Col. Grevemberg is a rare, World War II antiaircraft artillery officer who took part and survived five amphibious landings in the Mediterranean.

The American Doctrine for the Use of Naval Gunfire in Support of Amphibious Landings: Myth vs. Reality in the Central Pacific of World War II.

Mitchener, Donald Keith 12 1900 (has links)
The United States Marine Corps and the United States Navy developed during the interwar period a doctrine that addressed the problems inherent in the substitution of naval gunfire for artillery support in an amphibious assault. The invasion of Betio Islet, Tarawa Atoll, in November of 1943 was the first test of this doctrine. It has been said many times since the war that the doctrine basically passed this test and that lessons learned at Tarawa increased the efficiency with which the Marine Corps and Navy applied the prewar doctrine during the rest of the war. An analysis of the planning and execution of naval bombardments in the Central Pacific Campaign, after the invasion of the Gilberts, does not support this claim. This analysis leads the researcher to three conclusions. First, the Japanese developed defenses against many of the effects of the gunfire support doctrine that blunted much of the force of American firepower. American planners were slow to recognize the implications of these changes and, consequently, were slow to react to them. Second, many naval commanders responsible for providing naval gunfire support for Central Pacific operations still equated tonnage of ordnance to effectiveness of bombardment, regardless of their frequent references to "the lessons of Tarawa." Finally, strategic concerns and outright ignorance played a large part in determining the use of naval gunfire, the first taking precedence over the "lessons" and the second leading to the ignoring of the "lessons" all together.

Ordmånglarens Brunn Wordmonger’s Well

Ardelius Blane, Mercedes January 2019 (has links)
In my essay I am looking at the common heritage of written signs and images through my own experience of attention deficiency and mental illness. Through this lens of experience in which words and images are vividly transformed and merged, I am reflecting on language and art and their overlapping. Throughout the text I reference early written entirely pictorial languages, the painterly terms of thought disorders, as well as how the images that gave name to the characters in the phonetic alphabet is still lurking in the very letters themselves. I also exemplify how attention deficiency can evoke new image/text hybrids in a chapter I call ADHD poetry. In my own artistic practice I am drawn towards a melting point of language, written sign, image, high and low, illusion-representation-materiality, intellect and intuition. The surface as a physical object and idea – that there is a two-dimensional space where we project fantasies and fiction. Through prose, play, rhythm, rant, word salad, crumble of meaning etc. sandwiched, I am observing the swelling of words.
