W-3s
W-3s often have invaluable skills and expertise and are found in various military branches like the Marines and Navy. Such servicepeople earn anywhere from $4,261 to $7,474 per month, and those with 26 or more years of experience earn that higher paycheck.
W-4s
You can only be a W-4 if you’re in the Coast Guard because the Army, Marines, and Navy don’t offer this rank. Still, you could earn $4,665 to $8,691 each month. It’s lower when you’ve only got two years of experience and at the high end for those with 30 or more years in the military.
