A direct hit!

1/5 TARGETS DESTROYED

That makes two!

2/5 TARGETS DESTROYED.

Side note: Heavy weapons can only be used once per turn, light weapons can be used thrice per turn and medium weight weapons can be used twice per turn.

(Yes, Sniper Rifles are Heavy. On an unrelated note, Dartling Guns count as Heavy, mostly because one action counts as "point in general direction of enemy and squeeze trigger."

Hoping your arms don't fly off does not count as an action.)

3/5 TARGETS DESTROYED.

You're almost there. You can literally just say that you finish the quest next post and it will be done.
