Here at my current section, we get a copy of 'Soldier' every month and I must say that it's very good.
Soldier magazine is by far the best Mil publication I have come across, even beating the Aircrew Manual. It has content people actually want to sit down and read, rather than things people want published. That may seem a little subtle, but makes a huge difference.
What happened to 'The Officer'? That had some decent articles and the editorials had no bias, and were often quite critical of the MOD and Government.
....Hmmm, perhaps I've answered my own question there!
