What is the issue / bug you have encountered? Give us a short description.
Ranged upgrades only have half their durability, rounded up. Tested with all 4 upgrades:
Fire charge: 8
Gravel: 8
Emerald: 3/23 (gem/block)
Snow: 3/5/10 (ball/layer/block)

How can it be reproduced?

1. Give any soldier any projectile
2. Count how many times it's used before it breaks (against a bricked diamond soldier)
