侵华日军第七三一部队罪证陈列馆公布了原731部队海拉尔支队《身上申告书》档案，共185页记载156名成员的信息[1]。档案中记录了这些成员的姓名、军衔、入伍时间、岗位职责、调动轨迹及战后去向[1]。
日军通过虚假身份掩盖细菌战的真实目的，假借满洲第97部队、第177部队、第201部队等常规步兵部队名义征召人员，随后经731部队本部3个月的培训后，将这些人员分配至海拉尔支队[1]。位于内蒙古自治区东北部、靠近中蒙中苏边境的海拉尔支队，是日军对苏发起细菌战的前线基地[1]。
档案证实战后苏联对日本细菌战罪行的持续追责，156人中有145人在战后被苏军抓捕并羁押于苏联境内[1]。其中4人于1950年4月至9月间在伯力接受审判[1]。
The Exhibition Hall of Evidence of the Japanese Army's Invasion of China has unveiled archival documents from Unit 731's Hailar Detachment, revealing how Japanese military forces disguised their biological warfare operations under the guise of conventional infantry units [1]. The archive, comprising 185 pages, contains records on 156 detachment members, including their names, military ranks, enlistment dates, job responsibilities, deployment histories, and postwar fates [1].
Japanese military authorities recruited personnel ostensibly for standard infantry units, including the Manchukuo 97th, 177th, and 201st detachments [1]. After undergoing a three-month training program at Unit 731's headquarters, these personnel were assigned to the Hailar Detachment [1]. Located in the northeastern Inner Mongolia Autonomous Region near Chinese-Mongolian and Chinese-Soviet borders, the Hailar Detachment served as a frontline base for launching biological warfare operations against the Soviet Union [1].
Following Japan's defeat, Soviet forces captured 145 of the 156 detachment members and detained them within Soviet territory [1]. Between April and September 1950, four individuals faced trial in Khabarovsk [1]. The documents demonstrate the systematic nature of Japan's biological warfare program and underscore the Soviet Union's postwar pursuit of accountability for these war crimes [1].
