Explosive implants don't seem to be actually explosive.
Konater brought this to my attention. Apparently explosive implants are supposed to only have a chance to gib, while also having a chance to cause breaches and such. After several tests I've found that ordered explosive implants only gib after testing it 7 or more times.
//What you expected to happen
Some of the implanted to gib, some to explode
//What happened
All 7 test subjects simply gibbed, and apparently this is bad
