Most model gamers think of the hobby in a 'build' mode and a 'paint' mode (and 'play/game' mode of course). I also think of there being an 'engineering' stage - this is distinct from just 'building' in that it covers modifying a kit so that it can be magnetised, open/closed, strengthened with pins/sprue or even just recut if grabbing parts from different kits.
I often quite like this part, as it involves thinking about how to solve something that isn't on the instructions. Often building in functionality or swap-ability it wasn't intended for.
Not all models *need* this type of engineering; some don't need any at all. But some need an extensive amount.
The marine drop pod is one of those models.
