With special awakening and spirit of zeon active, you can 1 shot most units at full health. To counter SP like this you have to use high HP units. If you ask why not build defense to avoid the the SP kill you then you are a noob. SP is a true damage attack, meaning that it does not take in your defense stat to calculate how much damage it deals to you. It only calculates how much HP will it take away from you. To avoid SP like this you have to have a lot of HP by putting on custom parts that increase your base health or use unit that have high HP.
