The best response in this situation would be: "Send a note to the credit bureau that you were in combat rotation for three months with limited ability to pay your bills but have caught all the bills and late fees up."
This response provides a clear and factual explanation for the late payments and indicates that you have since rectified the situation. It's important to inform the credit bureau about the context of your deployment, as they may have procedures to help those who are serving in the military.
