Consider the following premises. There is at least one x_5 for which x_5 is a soldier. For all x_5, if x_5 climbs a mountain, then x_5 is a soldier. For all x_5, if x_5 were a soldier, then x_5 is climbing a mountain. Can we infer the following from them? For all x_5, x_5 will not climb a mountain.
 From the fact that for all x_5, if x_5 were a soldier, then x_5 is climbing a mountain, and that for all x_5, if x_5 climbs a mountain, then x_5 is a soldier we can infer that for all x_5, x_5 is a soldier if and only if x_5 will climb a mountain. From the fact that for all x_5, x_5 is a soldier if and only if x_5 will climb a mountain we can infer that for all x_5, if x_5 were a soldier, then x_5 is climbing a mountain. Finally, from the fact that for all x_5, if x_5 were a soldier, then x_5 is climbing a mountain, and that there is at least one x_5 for which x_5 is a soldier we can infer that there is at least one x_5 for which x_5 will climb a mountain, which contradicts that For all x_5, x_5 will not climb a mountain. Therefore, the answer is no.
