How much a soldier gets paid a year?

Answer 1

It depends on a soldier's rank, their time in service, and any other allowances they may be receiving (such as housing, separate rations, hazardous duty pay, etc.).

Answer 2

In the US, it depends on their rank and time in the service. The higher the rank, and the longer they've been in, the more they make. There are also special bonuses for hazardous duty.

Because of this, it really doesn't make sense to quote a single figure. You can look it up yourself from the related link.
