Gen. James McConville, the current US Army chief of staff, joined Massachusetts Gov. Charlie Baker at the Boston Hope Field Medical Station Saturday where he called the coronavirus an "invisible enemy."

"We are in a war against an invisible enemy. The Covid-19 virus," McConville said.

McConville was later asked how he felt about the deaths of the veterans at the Holyoke Soldiers’ Home and he said, "The loss of life is absolutely terrible. We don’t want to lose anybody."

When asked if he has a message to health care workers as they fight this enemy, McConville said he was in Afghanistan when the Boston Marathon bombing happened. He said he was proud of the response by Boston and the commonwealth, then and now, because the community became "Boston strong, they became Massachusetts strong and they will defeat this virus."

Baker noted that tumultuous events like the Boston Bombing are usually visible, unlike the current fight against the coronavirus.

What we are dealing with here, as the general said, is an invisible, insidious enemy and if you go outside and you walk around, it looks pretty much the same as it always did except there’s nobody on the streets, there’s very few automobiles, and everything for the most part is closed," Baker said.

The governor said that dealing with this virus is "a different kind of battle than one you can actually see what you are up against."

This "will, in some extent, be a marathon for us as well," the governor said.
