The 58 Military engineers/line'ies were replaced with 5 civilians.
I've always though of the military as a manpower orientated organisation. You may well be a super duper techy/storeman/scribbly/painter, but you were always an asset especially when it came to "here's a rifle, guard this". I can't see the 5 civvies pulling guard duty, and I may be wrong, but I doubt a JPA terminal has manned a checkpoint. Do stations even do exercises these days?
