Frankly, i'm shocked this isn't a thread.
I don't think it really needs to be, as it is pretty well covered by the highly successful "Guys, let's see your HAMILTONS!" thread that's been running for the past 6+ years. (Probably can't miss it, but it is here: https://www.watchuseek.com/f357/guys-lets-see-your-hamiltons-183188.html
Every Hamilton Air, Field or Navy model is a Khaki. At the moment that's almost 3 dozen different models by name, not counting variations. Roughly 40% of the product line.
A "Field & Nato Combos" thread might be interesting, and I could probably dig out a Nato or two for it, but this is just kind of silly broad. Just my $0.02.
Anyway, isn't it traditional to start these kinds of threads with a pic of your own? I'll show you mine if you show me yours ;-).
