Your husband being in the military and in California you are eligible to part of his retirement. Don't sign anything without a lawyer, even with 6 years California will grant you a part of his 20 year retirement. Some states don't unless you have at least 10 years but California and a few other states are different. Your husband probably knows this and wants you to sign the paper hoping you are stupid enough to sign it. You also can get him in trouble for his affair.
