Sorry, I can't post this without the extra...

Answer 1

Your top-level node is a mapping which contains the keys Putty, C4, Airstrike, HGrenade, Flashbang, SpiderMine and Broodstrikes. However, there is "something" before Putty that ought to be a mapping key:value, but which lacks a key.
My guess that you have inadvertedly indented the first line, so that G-4_Cluster is no longer a key in the top-level mapping.
