Groton — The Naval Submarine Base will participate in routine training exercises between Feb. 3 and 7 that will include live automatic weapons firing with blanks.

Events involving live-fire training and drills with blanks are scheduled to occur between the hours of 9 a.m. and 3:30 p.m.

Some of the training events may impact traffic and base access as gates or roads on the base may be temporarily closed during the four-day exercise.

The exercise is intended to test the base's ability to respond to a variety of threats.
