In the military, as with Police Service, it was always important for us to “recon” a specific area in some way before making entry.

This was also used on a large scale and not just on entry into a residence or apartment.  Such a HAZ mat incident or Chemical attack.

Recon was very important so we did not have any of those “unexpected” issues arise that can cause more damage, especially when not prepared for them.

Here is the “recon” with the surrounding communities of the Santa Clarita Valley.
