It's always a special moment for a designer to see their game on the shelf of their local game store. It's the culmination of a long journey. So please share your photos of Littoral Commander below. I would love to see them! 😁 #wargaming @labyrinthdc @FoundationDietz

LC Baltic. Partida de despedida de LC. La propaganda rusa habla de la OTAN escudándose detrás de civiles ( los cubos grises). La realidad verdadera es que la población huye ante el avance sobre Riga de los invasores rusos y marca la línea de contacto.

リトコマ会で海岸堡 BeachheadをUS側でプレイ 電子攻撃やBM攻撃による消耗と出目の悪さとルールの確認不足があり序盤は劣勢だった 中盤は立て直し上陸部隊の2/3を洋上で撃破 終盤は台北に迫るPLAに対してB-1、B-52による爆撃を行なうも相次ぐBM攻撃により台北は陥落した

NEW: The Taiwanese government is continuing to enforce its policies that require the elimination of People’s Republic of China (PRC)-made software and other PRC-made components of critical technology supply chains. Taiwan is working to develop “red-free supply chains” to eliminate dependencies on PRC-made technology to protect its supply chains and prevent opportunities for PRC sabotage. (1/2) Other Key Takeaway: The US Marine Corps and Japan’s Self Defense Force will both deploy anti-ship missiles to Yonaguni Island, the Japanese island closest to Taiwan, during the “Keen Sword” combined military exercise. The People’s Liberation Army (PLA) is likely concerned that the United States and Japan will contain the PLA surface fleet and deny PLA control of critical maritime chokepoints around Taiwan.
