I could easily fit this combination into a 6" square with space left over, or with the infantry side by side but less extra room, for grid games. Placing the vehicle behind or next to infantry/guns facing forward or backwards could indicate statuses - like infantry embarked, gun deployed, etc, in non-grid games.
Here's what the same vehicle looks like next to a CTS 1/38 PZ. IV .
