If I actually associated the decals with war, say in the manner of a bloody stump, they wouldn't be very endearing. My reaction was closer to Wallace and Grommit, so you can see there is a huge disconnect there. Had I actually served in either of the big ones I might not find it so humorous. I feel very fortunate that I did not.
But since M3w doesn't come with pair of machine guns, or any real military utility, I feel OK with the admittedly whimsical styling, in somewhat similar vein to the fun of watching Spitfires circle Duckworth, without thinking too much about their actual purpose.
Funny enough, I was in Tuscany, admiring one of the hill towns, when I realized that the entire beauty of the scene was the result of once pervasive violence that forced people to build fortified cities at the top of hills. An ugly fact, yet a beautiful result.
