IF the croc wants to attack you it willl have to draw its self out. this is a bit risky and tricky but heres one option.
you need a marder II and a panzer IV. you sould go second. the marder should be 6 sapces away from the croc. the croc moves 2 spaces forward and you too move 4 spaces forward. you can now fire at close range. thi scan be tricky but you also have to have the panzer in postiotion. you have to flank the croc and attack its rear. if you both of these things at the same time then the croc can a. destoy the marder or b. disrupt the panzer. it may be easier to do it with 2 marders but you’ll lose atleast one of them. there’s a 33% chacne of destroyign the croc and 34% of damageing the croc. also instead of a marder in the front you can use a jagpanzer IV.
if you get a marder to go in the back and up close the odds improve to 50% destoyred and 40% damaged. the key is to succide a tank up front ( or just indanger it in the case of a jagpanzer) and then sneak behind the croc and fire. so any 15/13 attack tanks can be used.
