Optimal Army challenge: Forgotten prehistoric menaces

[JHG]

Pick two to protect you. The rest are out to kill you. Possible candidates:
-A Huanghetitan 
-2 Mapusaurus
-5 Megalosaurus
-3 Shantungosaurus
-7 Pentaceratops
-20 Hatzegopteryx
-13 Camptosaurus
-6 Scolosaurus
-40,000 Wild turkeys
Choose wisely!

I assume we pick two, like in the other threads of this format?

In which case, I'll go with the Shantungosaurus and the wild turkeys, to rely on sheer brute force and strength in numbers .

Yes, pick two. 
Those sound like good options but Huanghetitan maybe too difficult to beat with that composition. That and the Hatzegopteryx are the only combatants that can fly.
