do you really believe we will allow them to fire against us from 8km distance and will not be able to disturb and outmanoeuvre their fire distance, even if so, yes we will lose units through 8km distance, but we will reach them with our weapons because it's not a pink ponk or static battle, but a mobile warfare, we are mobile and masters in camouflaging!
"Fire and movement, or fire and manoeuvre, is the basic modern military low-level unit tactic used to manoeuvre on the battlefield in the presence of the enemy, especially when under fire. It involves heavy use of all available cover, and highly-coordinated exchanges of rapid movement by some elements of the squad or platoon while other elements cover this movement with suppression fire. It is used both to advance on enemy positions as part of an attack, or withdrawal from current positions under attack by the enemy. The moving and supporting (suppressing) elements may be teams or individuals, and may quickly and continuously exchange roles until the entire unit completes the manoeuvre objective. Some members will specialize more in different roles within fire and movement as fits their range, equipment, terrain, and ability to manoeuvre. This is usually applied to standard infantry tactics, but forms of this are also used with armoured fighting vehicles or when supported by artillery or air power."
