I have a few years under my belt* in the service.
Im not more into MIL watches than other watches.
I just like rugged watches, that dont easily quit on me.
I busted a manual chrono i Iraq, so brought a Marathon SAR as a primary and a Casio 5600 series as a back-up when on a tour in Afghanistan.
The SAR (Casio too of course - goes without saying) performed perfectly and Im well chuffed with it. It suffered not a small amount of abuse and extreme shifts in temperatures (50 celcius + during the day dropping to way too cold at night). Neither that nor blood, swear or dust (the latter which combined with the aforementioned sweat forms tough to defeat cakes of gunk in the nooks and creviches of a watch - yuck!).
Here the SAR, that I brought and below in the sandbox
* Riggers belt, as these are 'de rigeur' no matter your MOS.
