Bought with a group of similar titles for my military mad 8yo. Recommended by a teacher for some variety to his reading. "Fun, adventurous, and provided some facts about WW2 and its machines", he says. Contains 3 stories in c200 pages. Some vocabulary was quite advanced but he enjoyed and followed the plots mostly independently. There is some shooting and explosions, and associated "aaargghh"s but no gore and is nowhere near Transformer movie levels. The worst word I've found is "flaming".
A collection of commando stories from the old comics - my son who is 8 absolutely loves these - so much so he has asked for more. Having read command comics as a child I know how enthralling these stories can be - ageless!
