Battle for Tra Bong Vietnam: Events and Aftermath

Click here to preview or order. Although this is not technical, I thought I would give a plug for my e-book published in December 2018. You can access the e-book from a Kindle device or the free Kindle app for desktops and smartphones.

In 1970, I was an Army Fire Direction Control (FDC) specialist. I was stationed at Landing Zone (LZ) Cindy in Tra Bong, Vietnam. We had an Observation Post (OP) and a Searchlight (SLT) unit. Next to the firebase was an Armed Forces Vietnam (ARVN) unit of 100 men. Besides the helicopter landing zone, we had the shortest airstrip in Vietnam operated by Military AssistanceCommand Vietnam (MACV). Approximately 100 men were stationed at LZ Cindy.

The firebase had tremendous firepower with automatic weapons, 50-caliber, and 60-caliber machine guns including a Quad 50, Dusters, 8-inch and 175 howitzers, mortars, grenades, claymores, flares, etc.

We had a major battle in September 1970. That battle and how it impacted me and my FDC team is the emphasis of the e-book. The ebook is in the Kindle format and available from Amazon. Click here to preview or order.
