To complete this mission, you can use a heavy tank type NEXT armed with grenades. The best choice are Raiden arms. First, once you've landed on Big Box, Vaoh will attack you with his twin gatling cannons. Maintain security distances and fire lots of grenades on him. his next is really heavily armored but his weapons have a limited firing range. You can also use a lightweight next armed with hi-power laser weapons, which are effective ageist gleditsia's low energy defense. Wynne will defeat opening quite easily but you must deal with vaoh, or he will help malzel and may destroy wynne's next reiterpallasch, who is armed with powerful en-weapons but is a lightweight ac with low ballistic defense.
