Did you report the accident to your insurance carrier immediately after the accident? Contact your agent or the assigned adjuster immediately, inform them the other driver is filing in Small Claims Court, & find out what they are doing to negotiate a settlement and get this matter handled.
IF the damages fall within your deductible, YOU are solely responsible for paying the damages. Best you settle that before adding court costs, etc.
IF you have no insurance, you have committed a crime & can lose your license (& your military). Settle out of court immediately - pay the damages bill in full immediately. Or lose a lot more than some money. This should have been settled promptly because the other driver can still file a police report as well as sue you. That police report would nail your butt to the wall - no license, fines, etc. On top of damages, court costs, etc.
