W-5s
Army, Marines, and Navy servicepeople go directly from W-3 status to W-5s, and it’s the highest pay grade possible. You could make $8,296 to $10,956 each month, which translates to a six-figure salary for those with 38 or more years of service.
O-10s
Generals (Marines, Army, Air Force, and Space Force) or Admirals (Navy and Coast Guard) can reach the O-10 level. Their base pay is $16,608 a month or about $199,299 each year, but they’ve had many decades of experience to get there.
