Help for divorcing daughter

My almost 47 year old daughter is getting divorced from her 49 year old retired military  husband. He wants her to drop the Survivor Benefit Plan which costs close to $400 monthly and he will get a 15 or 20 year term insurance policy for $500,000 for her benefit. She has been a stay- at- home mom so her career prospects are unclear.  My concern is she could end up at 62 or 67 without the insurance or survivor benefits.  Any suggestions?
