M103 is a huge disappointment.

Lert:   No, he proved that he could do well in high tiers. His challenges were done by a very experienced and very skilled player. IE, the complete opposite of OP.   Garbad can make a tier 9 with a 50% crew sit up and dance dance. Probably. OP needs all the help he can get.   ... Preferably at tier 4 / 5.   @OP: Read this. All of it.
