The shared experiences of war are commonly known to forge strong bonds among the participating soldiers. Through focus groups (N = 36) and a quantitative survey (N = 340), this study explores the bonding effect of United Nations peacekeeping among Dutch peacekeeping veterans. The veterans generally experience strong bonds with members of their former military unit, which are expressed in the need to exchange memories, share feelings, and renew contacts with former unit members. Peacekeepers younger than 35 years of age and older than 55 experience stronger bonding and have more actual contact with former unit members. This is true as well for veterans who have been deployed recently (less than 5 years ago) or more than 25 years ago. Social bonding seems especially strong when veterans look back on their mission experiences either very positively or very negatively.
