I noticed the rockets on the diamond camo RPG are diamond encrusted, seeing as diamond is pretty much the hardest thing going should there not be more damage / bigger radius? Sort of like a nail bomb.
It makes me question how much money these armies have when they're giving out diamond RPG's...
Let's do some math shall we!
In the U.S an RPG rocket would cost: $5000 dollars because of it being illegal, one 2kt diamond is worth about $500 dollars, the gold plating would probably cost from $2-5000 dollars. And estimating by how the rocket looks, I'll guess that there's about 7,500 diamonds on that one rocket.
So that would mean $5,000 + (500x7,500)=$3,755,000 per rocket + the gold plating amount.
