Viper is a pop-up sabot battery that has a great DPS and range for considerably low costs. Built by all T2 land/air cons it serves the most basic role among the defences – to pump in big DPS. Its pop-up abbility makes it a great way to soak huge damage when needed. 

When you see your opponent focus fire on it – switch it off and use as a tank, while your other units do all the work.
