The Mortar Strike returns in Call of Duty: WWII. It appears in the Campaign and killstreak item in Headquarters. In Campaign, a character named Frank Aiello, who has a squad ability that gives the player smoke grenades to signal in a mortar strike.
In multiplayer, it's a 750 scorestreak. The user can select 3 target areas when activated. Afterwards, 3 mortars missiles will bomb the area of desgnation. One mortar missile bombing has a similar area of effect and effectiveness to the Glide Bomb.
When selcting 3 target areas, it's a good choice to prime on objective points like in Domination to eliminate hostile strongholds. However, when overlapping target areas due to the multiple location designations, it coverage and damage greatly increases.
Though the AoE and effectiveness is similar to the Glide Bomb, the results vary similar to the latter. When overlapping designations, it only targets one section. To improve the usage of this streak effectively, think strategically will offer the best results.
