Lets see here Mr Russian Troll, they have M777s and HIMARS both of which they were given have guided shells for, not to mention several of SPGs from other countries use them.
There are no DFCMs installed on M777s because they proved to be a security risk on the first few days. It can’t be used with smart munitions without it. HIMARs can fire GPS-guided munitions but they aren’t “shells”.
