With some terrain, there are effects such as "Bog", where he model furthest from sarge, and all other models within 3" of him are sucked into the effect, and can take no actions til someone else spends 1 action in base-to-base contact to free them.
My question is, If i have a 6-man squad, and 5 fall into the bog, the 1 remaining guy spends one action to get to base-to-base with the closest model, and spends 1 action freeing him. Can the now-free model use all of his actions to free another model, and thus cascade down the line to free all other models? or, are the models that fell into the bog automatically "activated" for that turn?
