Nothing too special, just the PLZ-07B of the PLAN Marines doing live fire exercise............
Notwithstanding their current love affair with the terrible smurf camo, the PLAN Marines have done well to field a comprehensive armored and mechanized force that is completely amphibious and light enough to be transported via land or ship in meaningful numbers. That means much for a rapid reaction force designed with agility in mind.
The 122mm caliber IMO is a very overlooked caliber, but is uniquely positioned between the 155mm cannons and the infantry carried mortars. Being light enough for rapid transport, yet still packs a respectable punch.
