In a breakthrough for biological science, Private Tan has officially become the first human to undergo complete petrification while waiting to return his SAR-21.

The 19-year-old conscript was last seen entering the queue during the early morning darkness and has since become a permanent fixture of the battalion's architecture.

The Armskote storeman, currently on his fourteenth cigarette break of the hour, remains unimpressed by the recruit's transition into sedimentary rock.

"Oi, your rifle still got carbon lah, don't play punk and pretend to be stone," shouted Corporal Lim, poking the statue with a greasy cleaning rod.

"I don't care if you are a fossil, go back and scrub until the bolt carrier shines like your botak head!"

Commanders have lauded the development, noting that a stone soldier requires zero maintenance and never complains about booking out late.

The rest of the platoon has reportedly started using the calcified remains of their comrade as a convenient hook for their heavy field packs.

"Walau eh, this queue move slower than my grandmother's bowels after a week of combat rations," remarked one dehydrated recruit.

Military experts suggest that the queue’s current velocity is specifically designed to prepare soldiers for the inevitable heat death of the universe.
