To clarify, I'm going with squad deployment here, running them as four independent units.
For that I'm using four transports.
If I understood correctly, if I used platoon deployment I could have the platoon transported by three Goblins (3 x 1 ton = 3 tons), but would then have to load and unload them at the same time from or to the same hex?
The infantry is just a nice side note, actually - 73 points that don't hurt. I may drop them when passing a suitable location, say a wooded area, a bridge, or something like that.
