This sheet calculates the remaining amount of raw materials you require to build any of the four workshop tanks in the current campaign, Metal Wars.
By default it is set for the Caernarvon AX, if you want the Lansen C, SU12244, or Type 62 you should input the required parts under "TOTAL REQUIRED" in column C.
You should input your current built and in-progress items under "TOTAL BUILT" in column H.
The Excel spreadsheet outputs the remaining amount of raw materials you require to build your workshop tank of choice, allowing you to easily view which raw materials you can reconstruct into others to finish your required parts.
