Forty-five Apple, an Ammo and Demolition unit, is assigned to a Recon mission to determine how the Germans are crossing a deep river to refortify an Italian city with tanks and supplies. These combat-weary 'Demo' experts resent doing recon, taking risks and facing the dangers normally left to "mud sloshers" (Infantry). The film focuses on the experiences and reactions of two men: Pvt. Sonny Lazzotti (the group's interpreter) and Lt. Jim Blaine, their commanding officer. Later, after the secret of the hidden route is revealed, the team goes into action and you get to see demolition techniques and procedures that I believe were never before portrayed in earlier WWII movies.
The film makes up for its lack of Star power with exceptionally realistic dialogue, performances, plot, and hard-hitting direction. "Tank Commandos" has a convincing, matter-of-fact feel to it that somehow reminds me of the Korean War movie, "Pork Chop Hill", and the very best of the TV series, Combat!
