Martin, nicknamed the Grim Reaper, full name Martin Beniro Etro Beltes, held the rank of Sergeant and was a veteran selected for the Air Force Special Command Group due to his excellent performance and had served for four years.
Since the Air Force Special Command Group undertook tasks of a particular nature, Martin had never engaged in actual combat since being selected. Instead, he participated more in training and exercises. However, before joining the Air Force Special Command Group, Martin had served in combat multiple times with outstanding performance.
Before joining the Air Force Special Command Group, Martin was an army sniper who, in combat against guerrillas and drug traffickers, had achieved the impressive feat of 76 kills and was called the Grim Reaper by his comrades.
Because of his exceptional performance, Martin caught the attention of Air Force Command. After a complex process, he was transferred from the army to the air force.
