The Gulf War highlighted the increased threat of chemical weapons , prompting the SAF to begin Individual Chemical Defence familiarisation training for its servicemen in 1991 . In response , 39SCE was raised on 1 December 1993 as a company strength unit at Seletar East Camp to develop a chemical defence capability , and to conduct training and experimentation in the areas of chemical protection , detection and decontamination .

Following the September 11 attacks , the Singapore Combat Engineer 's EOD and CBRD battalions have worked with Home Affairs agencies to provide security coverage for significant international events
