From the Publisher's website:
Terror. Sheer blind terror sublimated and spat back out of the barrel of an M16. The fear and isolation. The desperation to get out alive - just to get out and get home. A green hell populated by a people ho despise you and want to kill you. Or maim you. Or send you mad. This is the Vietnam War. This is GRUNT.
GRUNT attempts to be historically realistic, claustrophobic and packed with a great deal of nervous tension. GRUNT uses six-sided dice. Players take on the role of members of an infantry squad, part of the famous 1st Cavalry Division, their missions are frought with danger: snipers, booby traps, jungle ambushes, rocket-propelled grenades, friendly-fire ... and stress. Always stress, building up to unbearable levels.
