The SRV-75 is a medium sized fighter developed by Blacktron II for raiding convoys. The twin sawblades in the front allow the fighter to cut a hole into a freighter, allowing following troops to enter and secure the cargo.
The saw blades also proved to be effective in dogfights.
The lime you added is really nice... copying will ensue if I build a BTII something. The trans-neon green blades at the front are actually very good looking and pretty much define the ship. I don't care what people say, I am a huge fan of BTII!
