stick the deathstrike missle in a lot of large cover, mount the infantary platoon in chimeras, backed up by the hellhound (yes i do say go for the hell hound as it ignors cover saves) that way they form your fast defence for the deathstrike just don't put it somewhere that can be reached in 1 turn and it will do well.
p.s. hope u get better soon
