Thailand has had 18 military coups since they abolished the absolute monarchy in 1932, one every 4.5 years on average. This time around (the last Thai coup was in 2006) there are a lot more Tavor TAR-21 carbines deployed. The Royal Thai Army is slowly replacing some of their aging stockpile of M16 rifles and M4 carbines with Tavors. They have ordered a total of 106,203 carbines with 58,000 currently in service, which probably makes this coup the largest military deployment of Tavor rifles outside of Israeli conflicts.
Thanks to Whaleoil for the tip.
