yeah but the opfor controller guys were still sleeping at that time of the morning.
we did have some contact in the hide position, but tanks with thermal sights can make short work of them.
A couple of big guns a even more MG can indeeb be a good deterand. (if not against observation, then against beeing engaged)
Reminds me of one of grandpa's war stories. Similar setup(overwatched obstacle against tanks)
He was in fact only a young boy(13) sent out with 5 others to stop the US 3rd army from rumbling along what now the Autobahn A4.
They set up a barricade over the road an put themselfes in BP close to the point where they expected the americans to stop.
Soon there was the sound of incomming armour on the road, so they kept there heads down till they heard the tanks stop.
When they raised their head again they made a quick count: 4x Panzerfaust + 6x rifle against 30+ US tanks.
The did the smart thing: waited till the americans passed by and then buggered off home throwing away weapons and uniforms
