As is usual with GP, there are three main features in the magazine.

The first has excellent coverage of German FlakPanzers of WWII.
Starts with great coverage of the Flakpanzer 38(t) 2cm, all Flakpanzer versions on the Panzer IV chassis, the Kubelblitz and finally the 8.8cm Versuchsflakwagen (Pz.Sfl.IVc)
Also included is a superb 10 page photo essay of the 3.7cm Flak43.
Sensational close-up photos of every part of the gun and mount. The gun is on a ground mount, but the gun itself is the same as in the Tamiya Möbelwagen kit.

Following this is part 1 of the "Jimmy Manual", namely the 2½ Ton 6x6 GMC Truck CCKW 353/352.
What makes this really good for the modeller are the many line drawings of various components of the GMC. Covered here are the Chassis, Engine, Axles and the Suspension. The drawings are exceptionally clear and show all the detail on these parts. These are accompanied by many good wartime photos on the 'Jimmy'. A must for any GMC fan.

The final section is Part 4 of the German Army Uniforms series. Many photos with line drawings of person equipment carried by the troops.
