Thank you for the URLs. You might use Babelfish for the translation.

The 15cm howitzer and tow photos seem to me rather formal... and by the background they suggest quite a settled air base, with a Me321 (no engines) inside a hangar. What are these, tests? On the other hand, the armoured car pic does look like a living action picture, completely informal.

Also you have to bear in mind that the bigger the load the smaller the fuel capacity, so range decreases. Also, this is a damned expensive way to travel, in terms of resource consumption. A much more effective way to move stuff is by surface (rail or boat) So, to move an armoured car or an artillery piece there are better options.

Besides what I said above, an artillery piece by itself does nothing. You need a lot more to operate a battery, so you'd need quite a number of flights to move a battery, not to mention its battalion, and forgetting about the regiment. To me this photo is PK work.
