You need to counter the player's style not just the army they play. If the army uses a lot of psychic powers field librarians, if it's daemon heavy use Grey Knights. If they use Thousand sons, counter them with artificer armor or terminators. Plague marines are countered with high strength weapons, such as plasma weapons, meltas, lascannons. Infantry heavy armies can be countered by tanks and walkers.
Space Marines carry a variety of weapons based on individual chapters and what each Marine (or the squad he's apart of) is meant to do. Devastators carry heavy weapons such as las cannons and plasma cannons among others. Assault Marines are meant to get into close combat, so they carry pistols and close combat weapons like chain swords and power weapons. A standard tactical marine would carry a standard issue bolter, and they all would carry a combat knife & grenades.
