NSIAD-96-59 Army and Marine Corps M198 Howitzer B-262208
United States General Accounting Office Report to the Chairman, Committee on GAO National Security, House of Representatives December 1995 ARMY AND MARINE CORPS M198 HOWITZER Maintenance Problems Are Not Severe Enough to Accelerate Replacement System GAO/NSIAD-96-59 United States General Accounting Office GAO Washington, D.C. 20548 National Security and International Affairs Division B-262208 December 27, 1995 The Honorable Floyd Spence Chairman, Committee on National Security House of Representatives Dear Mr. Chairman: As you requested, we obtained information on the Marine Corps’ and Army’s reported maintenance problems with the M198 155-millimeter (mm) towed howitzer to determine whether these reported problems justify accelerating the development of a replacement weapon. We also obtained information regarding the Marine Corps’ and the Army’s planned development of a new, light-weight 155-mm howitzer. Active and reserve Marine Corps artillery units use the M198 howitzer for Background all direct support, general support, and reinforcing artillery missions. Army light cavalry units use the M198 for direct support, whereas airborne and airmobile infantry units use the M198 only for general support and reinforcing missions. The M198 howitzers, first delivered to the services in 1979, are approaching the end of their 20-year service life. Marine Corps and Army users of the M198 want to replace the 15,600-pound howitzer with a lighter-weight weapon to ease the operational burden on crews and to improve air and ground mobility. The Marines have found it difficult to tow the M198 over soft terrain, and only their heavy-lift helicopter can move the weapon by air.

Interview with Mr. Ronald Sikorski UNCLASSIFIED
US Army Sustainment Command Interview with Mr. Ronald Sikorski UNCLASSIFIED Abstract In 2003, the Army Field Support Command (AFSC) and the Joint Munitions Command (JMC), collocated at Rock Island Arsenal, Illinois, began a comprehensive oral history project aimed at chronicling a full-spectrum slice of the commands’ role in Operation Iraqi Freedom, Operation Enduring Freedom and the Global War on Terrorism (GWOT) broadly defined. Because the command was over 90 percent Department of the Army (DA) civilians and heavily augmented by contractors, the command realized by 2003 that they were managing the largest ever deployment of DA civilians and contractors into a combat area, and so, over 150 interviews were conducted focusing on the GWOT-related experiences of DA civilian members of the two commands during 2003 and 2004. Starting at the same time, Mr. George Eaton, currently command historian at US Army Sustainment Command (ASC), has conducted to date almost 200 more interviews with DA civilians, contractors and uniformed military personnel. This oral history project aims at delivering an overall picture of the activities and duties of the various components of AFSC and JMC and their combined efforts to support the Army’s worldwide operations. The interviews look at growing trends in areas of both success and concern, while also accounting for how logistics support commands have completely transformed operational- and strategic-level logistics since 2003. ASC personnel are forward deployed at every forward operating base in Iraq, Afghanistan, Kuwait, Qatar and Djibouti, among others. Indeed, what began as a small operation in 2003 has become a robust organization, globally deployed, and is now a key player in all four of the Army’s materiel imperatives: to sustain, transform, reset and prepare.

Howitzers and Seven New Regiments: Indian Army’S Game Changer in Mountainous Terrain
P K CHAKRAVORTY Howitzers and Seven New Regiments: Indian Army’s Game Changer in Mountainous Terrain P K Chakravorty The words of former United States Secretary of State Hillary Clinton at the India Today Conclave held at Mumbai on March 10, 2018 were, indeed, music for the Indian ears. She referred to India as a country which is accepted as a power that counts by both political parties across the United States.1 This has been possible due to the robustness of the Indian economy and its armed forces. ‘Make in India’ has been a flagship project of the current government and the Regiment of Artillery has left no stone unturned to modernise, with emphasis on ‘Make in India’. Modernisation of the Indian Amy is being undertaken to meet the two-front threats from China and Pakistan. For this, the focus is on Network-Centric Warfare (NCW). Like other combat arms, the Indian Artillery is currently in an NCW environment and has to provide surveillance and reconnaissance, resulting in target acquisition which would lead to engagement which needs to be monitored to undertake post strike damage assessment and ensure that the target has been destroyed. In NCW, the artillery shapes the battlefield, degrades the enemy’s war- Major General PK Chakravorty (Retd) is Senior Fellow (Veteran) Centre for Land Warfare Studies, New Delhi. 104 CLAWS Journal l Summer 2018 HOWITZERS AND SEVEN NEW REGIMENTS waging capability, destroys his field defences, communication sites, and logistics echelons, thereby paralysing him and, thus, accomplishing own mission. Along with the ‘Make in India’ projects, the artillery has been at the forefront of modernising its inventory with state-of-the-art equipment.

The Rojava Revolution
The Rojava Revolution By Aram Shabanian Over five years ago an uprising in Dara’a, Southern Syria, set into motion the events that would eventually culminate in the multifront Syrian Civil War we see today. Throughout the conflict one group in particular has stuck to its principles of selfdefense, gender equality, democratic leadership and environmental protectionism. This group, the Kurds of Northern Syria (Henceforth Rojava), have taken advantage of the chaos in their country to push for more autonomy and, just perhaps, an independent state. The purpose of this paper is to convince the reader that increased support of the Kurdish People’s Protection Units (YPG) would be beneficial to regional and international goals and thus should be initiated immediately. Throughout this paper there will be sources linking to YouTube videos; use this to “watch” the Rojava Revolution from beginning to end for yourself. In the midst of the horror that is the Syrian Civil War there is a single shining glimmer of hope; Rojava, currently engaged in a war for survival and independence whilst simultaneously engaging in a political experiment the likes of which has never been seen before. The Kurds are the secondlargest ethnic group in the middle east today, spanning four countries (Iraq, Iran, Syria and Turkey) but lacking a home state of their own. Sometimes called the ultimate losers in the SykesPicot agreement, the Kurds have fought for a homeland of their own ever since said agreement was signed in 1916. The Kurds in all of the aforementioned nations are engaged in some degree of insurrection or another.

Backpack Helicopter
Backpack helicopter Artist's depiction of a helibackpack with counter-rotating twin rotors A backpack helicopter or helibackpack is a helicopter motor and rotor and controls assembly that can be strapped to a man's back, so that he wan walk about on the ground wearing it, and can use it to fly. Its harness, like a parachute harness should have a strap between the legs, so that the pilot does not fall out of the harness during flight. Related are devices like a backpack helicopter which also include a seat and leg supports and are actually very small open-topped ordinary helicopters. (See also jetpack.) Several inventors have tried to make backpack helicopters, with mixed results. In theory, a helicopter would be more efficient than a rocket pack or jetpack, possessing a greater specific impulse, and being more suited to hovering due to the smaller velocities of the propelled gases. Examples which are pure backpack:- http://english.pravda.ru/main/2002/06/11/30172.html describes a Russian backpack helicopter. The Heliofly was a make which was designed in Germany in 1941 onwards. See [1] and [2]. Or search for Heliofly in http://www.altavista.com . Pentecost HX-1 Hoppi-Copter Rhyme (made in Japan) Examples which have a seat:- SoloTrek XFV (Exo-skeletor Flying Vehicle). See http://www.vortechonline.com for various models which have seats. They formerly also made a pure backpack model with two very long rotor blades driven by a little propane- powered jet motor at the end of each blade. GenH4 1 Backpack helicopters occur sometimes in fiction.
