Kill Command (2016) free

Set in a near future, technology-reliant society that pits man against killing machines. Against this backdrop an elite army unit is helicoptered to a remote, off-the-grid island training facility. What starts out as a simple training exercise for Captain Bukes and his tight-knit unit, descends into a terrifying battle to the death, as the marines discover the island is overrun by an enemy that transcends the human concept of evil.
