May I suggest a Fire Prism?

Under the 5E Template rules, they are now a superb flex-fire platform. Drop a large template (S5, AP4) for up to medium infantry swarms, or a small template (S9, AP 2) for heavy infantry or tank-busting. If that's not enough, combine fire two of them for a Large S6, AP3 (delicious!) or a Small S10, AP1 shot.

All that, and it costs the same as a Falcon! What's not to like?
