If you are a DCS simmer, you probably heard of Carsten Gurk, a rather active community member – and a massive bridge destroyer. Carsten is working on his most recent mission for DCS, for both single and multiplayer.
Amoeba Games has released a set of tools for sims, but one of the most impressive ones, for me, is their AGHTM library, which allows everyone to build their own transport missions in DCS.
