Coro CARES helped 3rd Battalion - Kilo Company - Platoon 3073 CRUSH the CRUCIBLE by sending hundreds of protein bars to keep them powered up during the difficult challenge. What is the Crucible? It is a 54 hour, 40 mile challenge that must be completed with only 8 hours of sleep total. This challenge must be completed for them to become Marines. Protein bars are the perfect ready to eat meal because they are light weight yet can help sustain the Marine for long periods of time. Coro CARES saw this as a great opportunity to help and collected hundreds of protein bars to aid in their effort to CRUSH the CRUCIBLE.
