 I'm Sergeant David Marlar and I'm an EOD team member with First Explosive Ordnance Disposal Company. Post-plastic analysis, in a nutshell, you were going down on a crater left there by a detonation and it's our job to identify what caused it. Without post-plastic analysis, we wouldn't be able to figure out what our enemy is using against us. EOD is important to me because it's an amazing job. I love the sense of fulfillment I get from doing this job. I love how no matter if you came to work at 6 a.m. and left at 9 p.m. every single night, you still would not learn everything that you could have learned that day.
