However, subsequent test-fitting showed that the MW40 Multi Caliber-derived battle rifle was a little too large for the GM Command, which was supposed to use a one-handed weapon concurrently with the ballistic shield. The large battle rifle seems too unwieldy to be operated with one hand, mechanical or not. Therefore, the battle rifle was switched for a bullpup machine gun taken from the HG 1/144 Guncannon First Type, which actually fits the GM Command's look much better.
The embellishments on the GM Command's shoulders, chest and front skirt armour are all spare, unused parts from the GM/GM set, being leftover parts from the HGBF 1 Runner (specifically from the HGBF 1/144 Gundam Leopard Da Vinci). They fit really well with the GM/GM design and do not require much work to use them; you simply paint and affix them to where you want the parts to go with a drop of super glue. Only the shoulders required some drilling to accommodate the red lightbars.
The third party POLICE waterslides decals work amazingly well, albeit a little too fragile for my rough handling. I never liked using waterslide decals even if I acknowledge their merits. For this build however, they are a necessity and I'm glad that the colour scheme fits the overall police theme, further accentuated by the waterslides. A 'GM' decal was also added to the chest unit to signal its lineage.
