Pistols:

Glock-18 (Terrorists) / USP-S (Counter-Terrorists): Default pistols for each side.
P250: A popular economical weapon choice.

Rifles:

AK-47 (Terrorists) / M4A4 or M4A1-S (Counter-Terrorists): Standard rifles for both sides.
AWP: Powerful sniper rifle but expensive.

SMGs and Carbines:

UMP-45, MP7, or MP9: Cost-effective choices when on a budget.
FAMAS or Galil AR: Economic rifle options.

Heavy Weapons:

Negev and M249: Heavy machine guns, rarely used due to their high cost.
