Today we pause and give tribute to the brave men and women who made the ultimate sacrifice. Those that put aside their own future to preserve and protect the very existence we wake up to every day.

Lost are brothers, sons, daughters, mothers and fathers. Family lines extinguished so others had the opportunity to thrive.

Selflessness. Bravery. Forged in the heart of the American soul. An indelible character so resilient we have helped change history and preserve humanity.

Remember them and their efforts.

Remember what their sacrifice has given us.

Opportunity. Do not waste it.
