Check the terrain first: narrow spots give better control, but look for natural cover—rocks, trees, or banks that hide you from enemy fire. Verify the water depth and current speed; a shallow, slow flow is easier to cross and less risky. Map the enemy’s sightlines; the safest points are where you can approach unseen and retreat quickly. Always have a fallback route ready in case the crossing gets contested. If you can secure the high ground on either side, you reduce the risk of a surprise attack. Stick to those criteria and you’ll pick the safest crossing.

Good point, no blind guesses. Pick a clear trail you can walk quickly, and keep the smoke ready to mask the move. That’s the only way to stay unseen.
