If you want to trust everything to Google, and you have reasonable connectivity to Google. Works for a lot of cases, but for things like emergency response and military operations (key targets for the work), one is often working with low-bandwidth, intermittent, mesh networks - choice is set up your own server, or go with a P2P approach, as we are. Also, Google Docs doesn't really do much for version control or allow any kind of process to be added. Now GitHub or Fossil might be better comparisons, but those are oriented toward software development rather than more general purpose document management.
