The Hill Fight of the Korean War constitutes an important chapter of the formative military conflict of the mid-twentieth century where the South Korean and other UN forces confronted the Chinese and North Korean forces. Currently, it has become a vital site of contested memory, especially in relation to the growing contest of power between the United States and the People’s Republic of China. Describing South Korea’s recent initiative of missing in action (MIA)/killed in action (KIA) accounting activities on these old battlegrounds since 2000, this article looks at how public actions concerning the remains of war are intertwined with changing geopolitical conditions. This will be followed by a reflection on the limits of the prevailing art and technology of war-remains accounting.

Following the end of the Vietnam–American War in 1975, the commemoration of the fallen soldiers of the Army of the Republic of Vietnam (ARVN) remains a difficult issue. The post-war Vietnamese state has marginalised ARVN dead from its national commemorative practices, while it has destroyed or neglected former South Vietnam memorial sites. This article provides an examination of recent efforts by local ARVN former combatants, living relatives of fallen soldiers and young Vietnamese to attend to the upkeep of the former ARVN cemetery in southern Vietnam. Based on participant observation and interviews, I explore how people care for the dead through regular acts of grave maintenance and religious rituals. I show that, through these persistent practices of care, southern Vietnamese engage in a form of memory activism to ensure the continual existence of the cemetery and lay claims to the right to mourn for the marginalised dead.

A half-century since its conclusion, the Vietnam War’s ‘work of remembrance’ in the United States continues to generate, even innovate, forms of homecoming and claims of belonging among the state, its military and veterans, surviving families and the wider public. Such commemoration often centres on objects that materialise, physically or symbolically, absence and longed-for recovery or reunion – from wartime artefacts-turned-mementos to the identified remains of missing war dead. In exploring the war’s proliferating memory work, this article examines the small-scale but persistent practice of leaving or scattering cremains at the Vietnam Veterans Memorial on the National Mall in Washington DC, against the backdrop of the US military’s efforts to account for service members missing in action (MIA). Seen together, the illicit and sanctioned efforts to return remains (or artefacts closely associated with them) to places of social recognition and fellowship shed light on the powerful role the dead have in mediating war’s meaning and the debts it incurs.

This article details the remarkable involvement of the Vietnamese population in finding and naming half a million Vietnamese missing-in-action (MIAs). The secrecy that characterised Vietnam’s military operations during wartime, and the overlapping claims and therefore control of the MIAs by the army and civil administrations in the aftermath of the wars, are the reasons behind unsolvable quagmires in Vietnam’s current war-accounting effort. The myriad of state actors involved who often work at cross purposes raises the public’s awareness of the incompetence of the state and calls for the participation of non-state actors. The latest potential avenue to solve the MIA problem, DNA forensics, is facing all kinds of challenges, such as the quality of the bone samples and the scale of the effort. War accounting has therefore become an open arena of public engagement and popular dissent, while significantly transforming the cult of the dead in Vietnam.

In the mid-1990s, the crime scene toolkit was revolutionised by the introduction of DNA-based analyses such as the polymerase chain reaction, low copy number DNA analysis, short-tandem repeat typing, pulse-field gel electrophoresis and variable number tandem repeat. Since then, methodological advances in other disciplines, especially molecular microbial ecology, can now be adapted for cutting-edge applications in forensic contexts. Despite several studies and discussions, there is, however, currently very little evidence of these techniques adoption at the contemporary crime scene. Consequently, this article discusses some of the popular omics and their current and potential exploitations in the forensic ecogenomics of body decomposition in a crime scene. Thus, together with published supportive findings and discourse, knowledge gaps are identified. These then justify the need for more comprehensive, directed, concerted and global research towards state-of-the-art microecophysiology method application and/or adaptation for subsequent successful exploitations in this additional context of microbial forensics.
